I've been told its almost futile to try it that way since you'll have to re-sand and re-prime anyway due to dirt, nicks, bugs, etc. There are also the concepts of "chemical bonding and mechanical bonding...to get certain paints to stick properly to certain pimers, there is a time window of opportunity (chemical bonding). When the primer has cured too long, then you have to sand re-primer before you paint. The recommendation I got was to use whichever primer you want, then paint over it with a coat of the appropriate type of paint for protection...even stuff in a rattle can. (color doesn't matter since you just want to cover it). I tried using epoxy primer and leaving uncovered and I drove the car. just a month or so later, the coating and the panel underneath it was starting to deteriorate. Dave & Tracy wrote: What is the consensus on using a zinc primer on bare metal ? . I know that traditionally it should be etch primer filler primer, topcoat. However I need to paint some sheet steel on the new rear driverside quarter with out painting other coats etc. So I am looking for a type of primer that is over paintable at a latter date. could do with something that when dry is as hard as Iron, to give max protection over the winter..
