Not just any epoxy primer --- you want an ETCHING epoxy primer on bare metal.... or a wash sealer.
But what you REALLY need to understand is that you must know what you're going to finally paint the car with --- and everything from the bare metal needs to be compatible with THAT paint choice. This isn't where you just go all random and buy whatever someone else says they use.... Paints today are SYSTEMS.... and need to be treated as such.
Do your homework first -- make certain you understand your paint from bottom to top.... or you'll end up with a compatibility issue.
