The plywood on this cab is not so nice (it was under veneer). It's much smoother, but after hours of sanding you can still feel/see the grain. I started with 80 grit sandpaper. I'm concerned that I'd be removing too much wood if I keep going, since I've already basically removed a full layer of thin wood when the veneer came off.

My goal is to be able to paint it, so I suppose I'm going to have to coat it somehow. What do you guys do in this situation? Is joint compound a bad idea? Sanding sealer? Many of coats of primer?

I'd love to hear how you'd tackle it. Thanks for reading.
 
Overkill? as in "regurgitated pap"? j/k

What is the cabinet? You'll feel some grain, and probably the best thing to do would be a high build primer, then sand, then prime, then sand, to even it out and fill the grain and imperfections in the wood. Kilz white oil based primer is recommended by many. I used it on a particle board cabinet, let it dry, then sanded it back down to very slick, and at that point what was mostly left of the primer was what filled the pinholes/low spots. Apply another coat, then sand it smooth and then apply your base coat.
