I just built new bathroom cabinets using oak face frames and oak plywood for the box. When testing wipe-on stains for color, I noticed the plywood isn't taking the stain evenly, even when using a sealer before the stain. (yes I bought chinese plywood from Lowe's - i've learned my lesson) It's like the veneer is so thin, the glue has penetrated it in the most pourus part of the wood. It looks awful, giving the appearance of water damage after the stain was applied? Any suggestions on how I can get a nice finish on these cabinets? Or am I resigned to finishing them natural? I tested a piece with just a clear finish and it looks fine.
