If you're in so cal you can take it to Nu-Tek powder coating in Anaheim. They have to chemically strip it and apply new powder coat in your desired color. However I wouldn't do this, there are plenty of people willing to trade for stock color. Just post it up in the FS section you might even make some money on this.
