Hole in my 74 230 w115 Wheelwell Repair.

When the weather gets nicer here in the Toronto area I want to tackle this job. Can anybody please give me advice on the gauge of metal ! should use?
Is it just a matter of forming the metal and using pop rivets, then applying undercoat? Or should i use fiberglass compound? The hole is 5 inches high and 3/4 of an inch across.
Thanks in advance!

I love to learn.. I dont always like being taught.

Hi Ted.
It would help if you post a couple pictures of your fender. The first thing you should do is clean the area and tread it with a rust converter to stop the damage. Hope you know how to weld or buy a book on body repair first to get some idea . You never ever use pop rivets on a car body unless it's the first of April. H.

20 gauge should do it.

lightly scrape old rust away and treat with rust converter.

you could then epoxy your patch in and seal edges with epoxy patch.

spray paint to finish on inside, if you want then also spray undercar with rubberized undercoat.

you could also do the patch with fiberglass.

obviously welding in a patch panel is "best", but sometimes other ways are what is called for considering the situation.

I fiberglassed mine 30 years ago and it has held just fine. I did it when I was younger and did not have all the skills and equipment I now have. The only time I see it is when the spare tire is removed which is pretty much never...
