I am looking at some crown molding, and at HD they have "Primed Pine" for
about 2/3 of the unfinished pine. From the back it looks like pieces
finger-jointed together, and then milled and primed.

Is this stuff ok to use? Will is hold up, not warp, etc? I imagine that
regular pine would be easier to cope joints, but the price difference is
hard to ignore.
