I will have many questions, but will deal with one at a time.
I have the entire front end (fenders, hood, grill) off of my YJ. Wire wheeled the paint off of the frame back to the tub. (Like so many things, it seemed like a good idea at the time.) I am planning on going with primer, and then some Tractor/Implement Enamel (with hardener). I planned on using etching primer. Question 1:, where the bare metal meets the original paint, will overspray of etching primer on painted frame rails be a problem. Question 2: do I need another coat of regular primer over etching primer, or will enamel go right over the etching primer.
Thanks for patience with my lack of knowledge.
