i have a question about primers or base coat rust preventative. im not a auto body man or painter ive hired a painter. He has primed all my parts in a zinc base primer that we agreed to a few years ago. Fast forward to now, i have him working on the tub he has done the body work and its prime time. he doesn't want to use the zinc primer he says its thick and clogs stuff up his words were "im not a fan" he says an epoxy primer over clean metal is all i need. on anything else i would agree, but the curse of the fj40 rust scares me to death. Ive been working on this project for a decade i don't want to ever have to do this again. whats your opinion should i insist on the zinc or am i being paranoid. He is the body man and a good friend of mine, and has been with me since the start of this project. He is right that stuff is nasty thick and kinda tough to sand. I wish i had the name of it but i don't have that with me. The tub is media blasted and clean. whats your opinion should i insist on the zinc or am i being paranoid. Thank you for your time taken to respond!
