Any way to fix this rust??
Is there any possible way to fix these rust spots, even if it has eaten through?? Special paints or something like that????
You would need to cut all the rust out and weld in new metal , then primer and paint. You can go the cheap way and cut out as much as you can, then treat with rust convertor, prime and then use some body resin like bondo to fill. Prime, sand and paint.
NAPA sells it and made by loctite it is called EXTEND and it converts rust to a paintable surface but you still need to do what Tom said and don't go the cheap way because you still need to get most of the big rust out of there for a good long lasting repair
