hey, i did exactly what you are trying to do. it does take a lot more work than it seems but it turns out great. my friend and i put lots of money into it, and dont forget u gotta buy the powder for every color u need. dont really worry about the oven thing...we've done many valve covers and other stuff and had no problems at all. and ya...the fumes are bad, but its definitely worth it. its also a good way to make some extra money but the kids in my school are cheap bastards who just wanna pay for powder and thats it. so good luck, and if anybody wants anything done, lemme know...
