Pitch the rustoleum, and go to any good auto body shop supply and get
some red oxide auto primer or some other type of primer, as they have
tons of various primers well suited for what your wanting to do...By
the time you spray the boxes, and clean up the gun somewhat, it will
be dry enough to shoot the finish coat on and be done with it
all......Rustoleum is just too chancey..Sometimes it dires quick other
times it takes days or weeks to dry.....


What Roy said. I've had excellent results and good fortune with auto type
primers. Make sure they're not primer-surfacer, though, unless you're
trying to fill minor defects and intend to do some serious sanding.
