primer for oil based paint

That's the usual way it's done. Water over oil is ok but oil over water is a no-no.

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.

Not necessarily; all you need is a primer listed to be compatible w/ the paint. There are latex primers that are so rated as well; it depends entirely on the top coat's published requirements.

That is not correct.

What he needs is a primer that is suitable for use on fiberglass, and a paint that is suitable for use with that primer.

I would NOT use an oil based paint on a fiberglass door. And mine came pre-primed.

He's not MIXING oil and water....either primer, properly cured, gives a dry surface on which to apply paint or wallpaper. Provided the primer is suitable for fiberglass, there should be no problem. For an exterior door, oil might be a more durable finish. Just read the labels.

The new third generation latex, as well as water born pre-catalyzed urethanes are more durable than just about ANY oil based paint.

Why not, and what would you use?

Seems to me oil-based primer is going to stick to just about anything as well as any paint can.

best primer is a solvent thinned epoxy, then a phenolic primer, then an 'oil based primer', then a water based primer.... water based epoxy primer probably right up there with solvent thinned epoxy primer......

-- only the worst stuff available at the box stores.

Why not oil based? Because good acrylic latex actually stands up better - and if you are going to use higher end paint - like automotive paint, the water born pre-catalysed urethanes are better than air dry enamel and less fuss than acrylic laquer or acrylic enamel.- and every bit as good on fiberglass.
