Yep. No reason not too if your parts are not in an area prone to chipping, like wheels and such. I have gloss on my parts and so far so good. I am going to try a little different process to see if I can make it more durable. It can only get better from here on. I will do the black powder first and then the clear over that before I bake anything. I was doing black first, baking, then clear, and then baking again. The black must be setting up too fast, so if I bake all at once it should work. IF not then I will only bake the black coat for like 5 minutes so it gets liquidy instead of 11-12 minutes. THEN I will put the clear on and bake for the 15min it needs. It should stick better then.....
