I was working on this beater of a truck I picked up for my too-frequent Home Depot trips, and had an idea for a way to coat a control panel.  I'm not sure if anyone has tried it yet, but a company called Dupli-Color makes a spray-on truck bed liner that comes in a can, like spray paint.  It's really durable, inexpensive (about $8/can), and has an interesting texture to it.  It comes out kind of bumpy like that self-adhesive vinyl that some people use.  The can I have is black, though they might make some other colors.
