I have been reviewing many, many articles, forum posts, videos on what steps "should" be done when having bare metal prepped for painting.. The goal is to prevent rust from forming, and trying to make sure the car lasts with a good paint job..
As I reviewed, some etch primer the bare metal first, then perform body fill, fixes etc.. then use some type of epoxy primer then sealer then more primer of 3-4 coats then continue on.. Others, body fill first, fix etc, then epoxy prime etc...then seal, then prime...
I just wanted to make sure that my bare metal was rust proofed before any painting..
I didn't find the right solution from the Internet.
