Ask HN: How To Paint a MacBook Pro?

I've got a 15 inch MacBook Pro and i want to put the logo of one of my websites(ExplodingWumpus.com) on the back cover. I know that getting it laser engraved is the best option but i live in Calgary, AB Canada and everywhere i've talked to that has a laser engraver is either not interested or wants way too much money. So the next option i've looked at is painting it. I was just wondering how you guys would recommend doing it and with what? Making a stencil and then using aluminum spray paint?
