Thanks mate

Can anyone advise me here? I sanded my primer down to get a smooth surface for topcoat. Unfortunately even with 320 grit I went through a few places, not like 100% down to bare wood but probably 80%.

So I feel like the white paint will hide after 2 coats, in more concerned about adhesion and long term durability. Several of the edges sanded through as shown in one of the pics. These are cabinet doors and the primer is kilz oil based low odor formula. Frame is poplar and panel is birch.

I killed myself sanding all these down by hand and not mentally prepared for another coat and sanding but if that’s what it takes….
