Roger,
This is a job you can do.
Krylon Fusion for plastic.
Stone paint, both available from Wally World.
Spider web paint from Mister Art, or Blick art.
Experiment on an old 2x4.
I can send you pictures of stocks that I've done.
Fitting a pad. If you've got a belt sander, then go to Midway and buy the jig for it. Again it's easy.
