Hi all
I,m painting fiberglass door
I have oil based paint
Do I need oil based primer


Nope.

I recommend Zinsser Bulls Eye 1-2-3. Just about the finest primer I've ever
used. It's water-based, and can go over or under any oil- or water-based
finish.
I would NOT use an oil based paint on a fiberglass door. And mine
came pre-primed.
