I am in the process of welding patchpanels on the bedside of my truck and was wondering what is the best thing to put on the backside of them.It's the S10 so yeah,,, the entire length needs replacing.So,,, I can get to the back of everything (after welding)except the wheel arch,,,it fits up against the inner arch.So I can't treat/paint the wheelarch after welding.
I have never used weld-thru primers because I have always doubted their effectivness.Do any of them really work? Or is there any product on the market that will with stand welding and keep rust from developing?
