I'm about ready to media blast my car and will be spraying a coat of primer shortly after. I figured I would go ahead and order my primer and body filler today, but I read somewhere that body filler didn't stick to epoxy primer. So now I'm unsure which primer I should use. It will be bare metal and I will still be doing sheet metal work after I prime it. I just wanted to get something on it so I didn't have to worry about flash rust.
