Hello Jimthej--
If the idea is to put a different "look" on the plastic veneer of the cabinet faces, this might work: Krylon makes a spray paint called "Fusion" which is designed to chemically fuse with plastic, such as lawn chairs (
http://www.krylon.com/). It works quite well, especially for indoor projects, comes in several colors, and most hardware/home/paint stores carry it. Of course, make sure the plastic veneer is well attached to the door substrate first.
Best wishes.
