Bob — I just want to make sure we understand how you are using the plywood … I typically only used the prefinished plywood for the carcass (sides, bottom, back) and make the face frame from solid wood … and boy is it helpful to not have to finish the interior of the cabinet(s). The plywood is only visible on the interior (when you open a door or drawer). I make no attempt to try and match the exterior solid wood components (face frame, doors, drawer fronts) to the interior pre-finished plywood, since you sort of never see them at the same time.
