Surplus Warehouse has taken to collecting up the QC fails, strays, and over-runs from places like TriPac and Conestoga. Those boxes are in all sorts of states of finish--in type and kind.
The sort of thing what would need a good scrub (or three) with TSP, before a full coat of lacquer-based Kilz primer. And letting each of those steps dry a full day before moving on to even thinking about a (or first) finish coat.
But, that's me, I've spent along time around casework and renovations and the like.
Often, the "least expensive" answer is to spend more up front, rather than spend a bunch of time wrestling with getting things to match afterwards.
But, I've seen people descend upon the old KMC clean-the-warehouse-out sales buying "an entire kitchen" up out of mis-matched woods, styles, and finishes, too.
