I’m salvaging/restoring an old pine exterior door for my house. I’ve scrapped it down to raw wood, and found the surface slightly deteriorated in places. I believe the door is sound and worth re-using, so I’m planning to coat it with epoxy where needed and repaint it.
My question is whether I can use regular latex primer over the epoxy, or do I need to use an oil-based primer or something else.
Thanks

I think white pigmented schellac like B I N primer would be best. You can use a coat of 50-50 boiled linseed oil/ mineral spirits and let that dry for 48 hours before you prime, as a preservative on bare wood.
what does the mfgr of the 'poxy say...
Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming
WOW!!! What a Ride!
Forget the primal scream, just ROAR!!!
The big thing to watch out for with the epoxy is "blush." After the epoxy cures, most epoxy, especially the less expensive brands, will have a waxy substance called "amine blush" rise to the surface. This must be scrubbed off before anything will stick to the epoxy. A good sanding of the epoxy after it has hardened will probably suffice, but srubbing with warm soapy water and a scrub pad couldn't hurt either.
Latex and oil paints should both work just fine.
Thanks, I was definitely planning to sand it first. Could I wipe it down with something like denatured alcohol or something instead of washing it with soap and water?
Wash it down with naptha.

You can use acetone or mineral spirits. Not sure about alcohol.
Water removes amine blush ( it's water soluble) better than any other solventLet's compromise and do it my way

Fine and good, but adding water to the material is not always desirable.
Adding water to which material?
I use West System Epoxy extenisively in wooden boats. To remove any of the amine blush, water is the best for "blush" removal. Wipe with wet cloth, wipe with paper towels. Remember, this waxy by-product of epoxy can easily be scrubbed off using green ( preferably maroon 7447 ) scotch-brite pads, but change towels often, otherwise, you can end up wiping off the blush, and then wiping back on. As long as the surface is clean, and dulled by scrubbing ( not glossy ) most paints will adhere ( "key-in" ) to the surface.Let's compromise and do it my way
