powder coating is a great. we powder coat our race kart frames and they last and last. no chipping and the best part is dirt comes off with a water hose. they actuly spray fine plastic dust on the part to be coated with a special static gun and after that they put it in a oven and bake it untill the powder melts to the frame. they even have temper coatings that change color when you touch them. ive placed some links in case your interested.
