They call it Rail dust, Industrial fall-out , even every time we brake the small metal particles seek a home in our paint work!
I just found out about this recently
I noticed little rust spots all over the car mostly behind the front wheels, on the sides even on the plastic body parts that should not and can not rust,
A buddy says brake dust!
He saw a new white pick-up covered with little rust spots caused by brake dust!

The hot particles stick to the paint and if not removed they will eat the paint to the metal then you have rusting door bottoms etc...

I have a light coloured car so they showed up easy
Some colours they will be harder to find
My first searches, I found they can be removed by clay baring and then protecting the paint with a good wax or paint sealer
I just heard about another white pick-up owner that had taken out an extended dealer paint warranty and when he showed them the rust spots they said the warranty was void if he didn't get the truck acid washed..!
I said "wwwhat!"
I am still researching on the best way to proceed

IFO

here's someting I found:

Someone else asked me to write this article for them and I figured it was TI worthy so I'll post it here too. For anybody who doesn't want to read the whole thing, the second to the last paragraph is basically the summary of the whole thing. I spent some time explaining IFO and how to protect yourself from it before the info on how to remove it. Hopefully it is helpful. I think something of this length could be written about every aspect of detailing probably. There is a lot to know, but its not too hard to learn if you are interested. The knowledge of how to do this kind of stuff is going to be the edge you need when you are at a show with a hundred other tegs that are just as modified as yours is. It will all come down to the condition and cleanliness of the paint in the end.



What are those orange dots and how to I remove them and protect my car?

By: Anthony

The orange dots that most white car owners see and many other car colors simply hide is called Industrial Fallout (IFO) and is also known as Rail Dust. IFO occurs when particles from the atmosphere land on an unprotected car surface and then embed themselves in the paint. Typically this kind of thing is caused by brake dust if you do a lot of freeway driving. Hot brake dust coming off your brakes and the brakes of other drivers will land on your paint and melt right into the car much quicker than other forms. Rail dust is similar. Rail dust is named such because it is commonly found on cars that are transported by rail. Metal shavings from the rails fly up and melt into the car the same way brake dust does. It is protection from these kinds of IFO that cars are shipped with those protective plastic sheets on the hood and side mirrors and other parts of the car.

IFO also literally falls out of the sky. If you live in an industrial area then you are going to see more of this problem than if you lived in the country. Living near refinerys like I do puts me at greater risk of IFO than the average joe. Compound the fact that I have to do some freeway driving and I live a stone throw away from the freeway makes me even more at risk. Polution from these areas will collect in the atmosphere and just land where it falls. Usually that is going to be on cars parked and not doing anything.

The only way to 100% protect yourself from IFO is to never drive your car and keep a car cover on it. That not being an option for most of us, the other alternative is to protect the car in other ways. Keeping it washed is the first good way to prevent it. In the winter IFO is even worse than in the summer. All that brake dust and polution that doesn't land on your car right away is quickly deposited there in the form of slush and road spray. Ever notice how bad your car looks in the winter as compared to the summer? People go longer between washes because it just gets dirty again. That is not a good excuse. The same argument could me made for washing your dishes or cleaning anything else. What's the point in brushing your teeth? They are just going to get dirty again. You need to keep your car washed weekly if possible. In the winter when it is hard to get out there and do it then you need to at least take it to a drive through car wash or something. The paint on your car is the most expensive part of the vehicle. Even more expensive than the engine or anything else. It is also the most visible part of your car. If you ever plan on selling the car someday then you need to take care of the paint. That will be its best selling point when the time comes. Don't let your lack of washing it cost you hundreds or thousands of dollars on the resale value.

Another good way to protect your car from IFO is to use a high quality sealant on the surface. Waxes are great and everything, but they are merely for looks. Waxes won't protect you from IFO for very long. Imagine dipping your finger in a candle that has just been blown out. I remember playing with wax when I was a kid and I would do this all the time. The wax coats your finger and creates sort of a shell around it. If you bend your finger and then straighten it back out again, then you might notice that it isn't a skin tight shell anymore. The more you wiggle your finger the shell gets looser and looser. That is how wax works on your car. It creates a 'shell' around the paint that is temporary protection. In the heat your car will shrink a bit. When it gets cold it will expand. This shrinking and expanding will create space between the paint and the wax. Heat builds up in that space and will speed up the process of the breakdown of the wax. Even the best wax will only last around 6 weeks on your car before there are large areas of wax that have basically 'melted' away. Harsh weather like heavy rain or snow will wear down the wax as well. Using really strong soaps to wash the car will wear it down too. Wax is very oily, so using an oil cutting wash will pretty much remove all the wax. Dish soap is a very good example of this.

A car sealant is more like dipping your finger in super glue rather than wax. Super glue bonds to your skin right away. It will shrink and expand with your finger instead of pulling away. In fact, to remove the super glue you may need to use an abrasive pad or some other strong chemical. Sealants bond to your car in the same way. They bond on the molecular level. First the molecules bond to each other and then they bond to the paint. This creates a very strong barrier of protection that can last for many months. Some can last for 6 months or longer. Sealants are very good protection for your paint. There are many different kinds of sealants that provide a variety of appearances. Most are very glossy and shiney. The latest technology of sealants adds a depth and a 'wet look' that has always been the best quality of waxes and glazes. Now you can get the appearance of a wax and the durablility of a sealant.

The best part about a sealant is that it will protect your car from UV rays that will fade the car and oxidize it. It will also create a much slicker surface that IFO finds much harder to penetrate. If you have a good sealant on the car then IFO may land on the car, but it won't be able to work its way into the paint quite as easily. It will wash off instead of needing other treatments. If you live in a higher risk area for IFO damage then it is important for you to wash your car frequently and use a good sealant.

Now comes the part where we deal with removing the little brown dots. The reason they are brown is because most IFO is actually metal shavings and they rust when they get stuck in there. The brown stain is the rust that spreads from the little piece of metal. The rust stain can be cleaned off easily enough with a paint cleaner or a polish. That won't remove the metal shaving though. It will still be there. With enough of those metal shavings in your paint you could cause serious and irreversable damage to your paint that will eventually result in total clear coat failure. You have seen it before I'm sure. Cars that look like the hood needs to be repainted are cars that were badly taken care of to begin with. I've seen 15 year old cars looking better than 5 year old cars and it is all a result of proper car care on a regular basis.

The proper way to remove the IFO is to use a product called 'clay'. Not molding clay or earthy clay. This is a specifically designed for automobiles kind of clay. Clay Magic is the brand that I would suggest. You will find other brands on the shelf from companies like Mother's or Meguiar's, but Clay Magic is the brand that I like the best. I like it best for a number of reasons. Number one is the way that it sticks to your fingers while working with it. Some clay is just too hard and slips out of your hand too much. If you drop a clay bar on the floor then it is going to pick up little pieces of grit that are going ot do damage to your car. A dropped piece of clay is a lost cause and should be thrown away for safety. Clay Magic is sticky and I very very rarely have one slip out of my hand while working with it.

The way you use clay is very simple. You wash the car and rinse it like normal. Dry it as you usually would, but leave a little water here and there to help in lubricating the clay. Clay Magic usually comes in a kit that includes a bottle of spray lubricant. Using that with the extra water on the surface will make the job much easier.

Clay usually comes in a 100g sized bar. You can break that into three or four pieces very easily. Break off a chunk and begin with that. If you drop it then at least you didn't just throw away an entire bar of clay. one clay bar is good to clay probably half a dozen cars or more. You shouldn't need to worry about replacing this bar often. You won't really have to use it that often.

Using the spray lube provided with the kit, spray some lube on the surface of the car. I like to start with the front of the car on the hood or the fenders. Don't go too heavy with the lube. Just a spritz is really all you need. Then going in back and forth motions in the direction that the air blows over the car while driving, go about 10 or 12 inches at a time. Just rub it back and forth along the surface untill you have covered the whole car. Do not use clay in circular motions. Go in straight lines from front to back. Don't go up and down or in circles. There is no need to wipe down the area after you are done either. Usually I just pull the car back out of the garage and wash it again when I'm done. That is actually the easiest way to do it.

Claying your whole car should take about an hour. once you get good at it then it is possible to cut that down to 20 or 30 minutes. Its not a very hard job to do and the difference after claying is amazing. You will notice that the surface is noticiably smoother and has more shine. As you are claying you will feel that the surface grabs at the clay at first and then allows the clay to glide after a couple of passes. That is how you know the clay is working. It isn't rocket science at all. I am amazed everytime I explain the principle of clay to someone that they have never heard of it before. This is the easiest way to work by hand and actually repair damage and prevent future damage on your car.

After claying your car you can follow it up with whatever paint cleaner or polish you normally use. While clay will remove many of the black and brown dots that are caused by IFO, it may not remove them all. Using a good paint cleaner or polish will clean off the rest of the stains. The metal shavings are gone and all that remains is the stain. That should be easy to clean up as prepearation for a selant or a wax.

The only risk involved with clay is that you may pick up some grit in the clay and it could act as an abrasive on the car causing scratches. To avoid that, you should fold the clay often and inspect your work and the clay frequently. If you feel rough particles in the clay then you should try to either get them out of the clay or get a new piece. Folding only helps so much. If you have lots of gritty particles in the clay then its time for a new piece. Its not worth the scratches you could cause in the car if you choose to ignore the particles. Clay is cheap at a price of only about 10 bucks. Your paint is worth buying a new bar if you have run out instead of using a piece that is gritty and could cause damage.

To store your clay you should either choose a zip loc bag or some other kind of container that will protect it from dirt. 200 gram sized bars of clay usually come in their own box. I store my clay in an empty wax jar. Choose whatever works best for you. Protect the clay from dirt and it will be there to protect your car from IFO for a long time.

You should only really need to clay twice a year. I clay in the spring to clean up from the winter and then I do it again in the fall as I prepare the car for the winter. Unless you notice the orange dots coming back then you shouldn't need to clay more than that. The most common place for IFO to appear is the back bumper and trunk. That is where your own exhaust deposits polution and the wind blows your own brake dust behind you. Those areas may need to be clayed more often. Follow clay with the sealant or wax you normally use.

Well, that may seem like a lot of work, but it really isn't. This article is mostly informative rather than actual instructions. To summarize what is written, these are the steps you should follow:

-Wash the entire car with the car wash of your choice. You may leave a bit of water on the surface when drying to assist in the lubrication of the clay. To clay you just lubricate the surface with either a soap and water mixture in a spray bottle or with the lube included with the clay kit and glide the clay along the surface. Do not use circular motions. Rub the clay on the paint in straight lines from back to front in the direction the wind blows over the car while driving. The clay will grab at first and then glide with ease when the surface is clean. Do not drop the clay. Inspect it often for grit or other particles that could scratch. Clay the whole vehicle and then rewash the car. Apply a paint cleaner or polish to remove the remaining brown dots and then seal or wax.-

That is as much as I think I can say about how to handle those annoying dots that appear on your car. Don't just polish the car and be satisfied that the brown dots are gone. Protect the car properly with a sealant and remove the IFO with clay. That way the dots won't come back unless more IFO penetrates the sealant. Keep an eye on your car and care for it well and your paint should please you for many years.

It is from snowplows. Not industrial fallout.

I had a car's paint destroyed by industrial fallout, and believe me it does not polish out. It eats little pits into the paint. This was in Trail BC (lead-zinc smelter) and it is a big deal.....

I must live in a cleaner area than most.

The big cities do have an Orange dome over them when viewed from afar.

Whether it's Sudbury or Toronto or Montreal, ..most of the big cities can damage your paint over time. Where you park can make a big difference too.

Proper cleaning is essential followed by sealers and wax and that should keep the paint in "near new" condition. ...but my B is RED , so maybe I'm missing some of the red spots too........:D

exactly,location makes all the difference!
I first noticed the rust spots after my car was sitting at the MB dealer for a month it was like someone had sprayed little orange dots all over...
The dealership is in a industrial zone sitting between two railways with a very busy scrap yard within two blocks and I believe they have a car shredder.
The thing is that there are about 6 new dealerships in that area,with all the new cars sitting outside???

I've also parked beside locomotive yards. Old (and newer) locomotives consume a lot of crankcase oil due to their design and "blow-by". If an old loco gets throttled a lot (as in a switching yard) where they go back and forth all day long, then your car can be coated by dots of dirty acidic oil in just one windy day. That cloud of dirty sooty smoke can dot your whole car in just one pass by.
Always stay away from belching locos,.. and if possible, don't park beside any tracks.

The cars sold new in BC often have rail crap on them after the 5000 km rail journey. These rusty orange spots...

If you look at roads in heavy snow areas in summer, where the snowplow blades hit the asphalt, there are rusty spots. This is what causes a lot of the spotting, there are tiny metal shavings all over the road. My Peugeot 405 had tons of that stuff when we lived in the West Kootenays and there was virtually no rail traffic there but lots of snowplow use (and orange stains on the asphalt).
