Not sure if this is appropriate to post. Did some searching but could not find a definitive answer:
What is the best primer/paint to use on exterior doors?
The doors are fiberglass, made to look like wood. They are unprimed and unpainted. I live in NJ and get temps from 0 deg in winter to 100 in the summer. It'll probably get about 7 hours sunlight/day.
Any help appreciated.
