Replaced some hollow-core luan interior doors. Matched the stain no problem. The poly is giving me fits. I thought it was at best a semi-gloss, so that's what I put on. Once it dried, it became pretty obvious it should have been a gloss finish instead.

So... can I just use some 220, lightly sand then go over the semi-gloss with gloss and get the sheen to match the surrounding trim? Or do I need to sand all the way down to the stain and start the poly from scratch?

Or is the difference so slight nobody but us would notice? We want to sell this place in a couple of years, and the work I'm doing is towards that thought.

Can anyone help head me in the right direction?

Thanks!
