I think if you're wanting it to go back white I would try the methods in the link ghostrider provided. If you're wanting to paint it a different color I say go for it! I've used the Krylon fusion paint for plastic before and had great success. Some of the decals I've seen look nice too but I wonder about their longevity with the heat of a machine that's used a lot. I have often wondered myself why the machine's don't come in different colors or at the least with a matte finish.
