"Temporary" Primer for Fiberglass?
I'm about done with the project and have come to the conclusion that painting will happen later rather than sooner. With kids and family, I've got more important priorities for the $$$ it would take, and the plane will fly just fine for a while without paint anyway. Given that it will be awhile, I'd like to prime the fiberglass parts gray just for the sake of aesthetics. But, since I have no idea what finish coat I (or somebody) will be using someday, I can't really select the "right" primer to use.
Can I just use a cheap primer that I will plan on sanding off before the real paint job? For example, I already primed the top cowl with a can of Napa 7220 and it looks great and is very easy to sand off. Probably some lacquer thinner would make even quicker work of it. Can I just continue this route and use something like the NAPA or Rustoleum primer and not put myself in a world of hurt later on down the line? What have others done here?
Thanks for any suggestions.
