im pretty much done w prep/body work on my car, i used i think duplicolor filler primer and rustoleum automotive primer... should i worry about the mix of these diff manufacturers?

also, im tossing between napa crossfire paint and rustoleum protective enamel (gloss black)

which should i go with... my buddy dan used crossfire to repaint a hatch aztec green and he didnt find any probs with the paint.

tho im iffy about rustoleum... because ive got bad paint from them before.

 

If I were you I would reprime the entire car with a quality automotive primer. If your mixing primers your asking for variations in the paint on those areas. Possibly even adhesion issues
