I recently completed building a cabinet drawer to convert a free standing vanity into a dresser. I'm aware that drawer interiors are often left unfinished, but it's quite humid where I live and I wanted to mitigate wood movement as much as possible.
The existing drawers have a fairly smooth, clear finish on them, but I'm not sure if it's polyurethane or something else. The reason I don't think it's poly is that it doesn't have the characteristic "grabbiness" (high coefficient of friction) that most polyurethane coated surfaces do. It's almost more of a sealer. Any ideas on what it is? I'd like to match it if at all possible.
