no NOT Body By Jack crap
Ok, Here it is. I am restoring/upgrading a Mercedes Unimog 404.1. I'm now doing body work that is welll... body work. Don't matter that it's a Unimog so I'm posting here for everyones benefit (particularly mine
) I'll include some links on the history of this project
to get you folk upto date.
A giant rotisserie was built to make the project easier to work on.
Doors removed, Passenger Fender Removed
(ruined in the process, but that is OK). So now Im planning ahead for dealing with RUSTTTTTTTT. and paint removal.
RUST Plan- remove it physically, use OSPHO to treat it
Removal of Paint Plan- using Elephant Snot (Aircraft Stripper) to remove it. Use spray can Etching primer as a coat to prevent rust on parts as I remove paint. Will move up to a spray gun once I get water filters onto the air compressor line.
In picture one is a hole that goes from under cab in a little corner. The hole goes into a storage space that sits under the passenger seat. It is sheet metal. Ssorta akward area to get at. What repair do you suggest after opening it up good and treating area with OSPHO? Fiberglass patch, expoxy (JB weld?) or weld it in some fashion. (Im ammature at welding - MIG is all I have) Area will get a cover of POR15 and Rhino type lining later.
In Picture Two is a small one and half inch "hole" in the doorjam (green area). It only goes thru outer wall of this area. There is another wall 3/4" behind this. Same questions as above. This question may change as I open the hole up further to get more cancer out. How do ya'll suggest I treat the rust inside this area while I got the hole open? the area is hollow and runs along door jam.
In picture Three is a BIG HOLE where rust ate away at the rear wall. Obviously I want to cut out and weld in a new piece of sheet metal. My quesion is about the bottom edges which is a frame of angle iron. The angle iron frame is the piece the sheet metal folds under and is tack welded too. This is is eaten away some. Structure strength still looks fair cause it is NOT all the way thru the angle iron. What do I do here after treating for rust on the outside and before replacing sheet metal ? Cut out frame and weld in new piece? Don't remove it just weld in a second angle iron on the inside of the cab for added strength? Fill in rust craters etc. by welding on it some beads and grind it down flush? Fill it smooth with JB weld type stuff? I pretty sure it would be unwise to cut out the curved portion of the angle iron frame. I don't really have the ability to match the curve with another piece.
