Okay this my be a silly question but I have to sand down (not to bare metal) the underside of the 1966 mustang hood (its black). Once its where I want it I want to primer. I planned on using Eastwood epoxy primer but is it okay to primer over the old (sanded) factory paint? I don’t want to treat it like the top of the hood (down to bare metal)
Should I just use a direct to metal 2K instead ?
