I've cheated a little on a part that wouldn't fit in my oven. I needed to do my roll bar and didn't really want to go to the hassle of bringing it somewhere. I preheated the roll bar with a torch and got it as hot as I could and evenly heated as possible (an infrared thermometer helps). Once I got it around 250, I dusted the powder coat on and it melted on contact. The only drawback was it had a little orange peel becuase it wasn't hot enough. It was even a two coat, silver base and blue candy.
