DO it your self its easy! http://www.eastwood.com/paints/hotcoat-powder-coating.html
i got an electric oven that was being trashed but it worked.(free) bought the $99. set up from eastwood.and it worked great on all the parts i did for my car. havent done any pin parts yet but they are smaller than intakes, blocks and heads. eastwood has 99 powders to chose from. i recomend extra containers. bigest thing cleaning gun and carefull not mix or get powder dust and contaminate colors. spray/ then 450 degrees when powder starts to flow another 10 minutes and done. small parts can use a toaster oven larger parts can use halogen lights. no worries practice on any thing metal. have at it!
