Sait 36 grit flap disc, if it has to be more clean or smooth I'll use an 80 or 120 grit. if it has to be powder coated I blast it with my NT sand blaster, but it takes forever! looks great tho.

what are you using for an oven? I have a little jet hot coating kit, never used it cause it seemed like a pain in the @$$. but now you got me thinking about my wifes electric oven... maybe she needs a new one, so I can have the old one....
