+1 for the Krylon on pickguards.  I painted a black pickguard and jack plate from a FV-1 kit with white Krylon Fusion for plastic.  Took a few thin coats to fully hide the black (put the first coat on too thick and had runs everywhere, so sanded back and started again).  Sticks like shit to a blanket.  I finished it off with a few coats of Krylon clear gloss for scratch protection.  Seems a bit weird worrying about scratch protection on a scratch plate, but hey.
Here's a can of black gloss a lot cheaper than I paid for my cans -
