I've never tried it with a bow riser, but I have powder coated some small motorcycle parts. There are a couple of issues with do it yourself powder coating. Your home over is small. To get the best finish you need to hang your parts. My home oven is not big enough to hang my riser properly. Second, when you bake the powder coating it smells. You really need to get a second hand oven, or you could ruin your primary oven because of the stink. With that said, the small bits that I did turned out nice. I don't have any pics or I would share.
