KPC,
All of the seams will be in the indent of the molding, and I'll be able to use the factory seam at most of the visable edges.
The only "unseemly seam"

will be at the very bottom where the factory seam crosses over the molding from the side to the front and back. There won't be any seams on the top or sides. Any place there's not a factory seam, I'm painting with thinned TB2, and letting it dry before cutting so theres no fraying.
