I powdered my forward controls this past weekend (with powder I’d purchased about 6 years ago!), and discovered, to my dismay, that they are about the max I can do in my oven. They touched the sides of the oven a couple of times, and now I have a few holidays. I recall that there is a method of dissolving powder in acetone (?) for touch-ups. Can someone give me tips on this? Do I just mix together to make a goo, then use a paint brush to fill in? What should be used to prep the bare metal and properly coated areas around the void?
