painting over poly

I have 4 solid core pine doors that I got for free. I want to paint them white. Right now they are stained dark and looks like an oil based poly finish. I can sand them of course and prime with a good primer. However i have seen deglossers and some other products to use before priming to help the paint to stick without the need to sand. Has anyone ever tried these, and do they work?

Just give it a light sanding and use a quality bonding primer like 1-2-3 or Fresh start. After the primer dries paint with whatever you like... No reason to use a deglosser or sand too much - the primer is designed to stick to that type of surface...

Painting over Poly

Bonding primer is a must. B79w8810 (preprite Problock alkyd) from Sherwin would be ideal. It'll give you the adhesion you need and block any stains that could potentially leech through to the surface. Deglosser can cause more problems than offer solutions. Scuff sanding is always a good idea when dealing with poly.
