Well after 50 some years of lube sizing I finally did it. Been wanting to try it for a long time but finally powder coated the first batch. Two years ago I ordered BBs and three sample colors from smoke. Last spring the youngest son was home in the spring. Its been a while since he has been home so he, I , and my grandson went out riding around to look at the changes since he has been gone. While we were riding around the grandson spiced a little toasted oven by the curb with a sign that said free/works. I got the boys stopped and jumped out and put it in the trunk. I'll be darned if it isn't a convection oven. When you get older life sometimes doesn't allow you to stick with your projects.
Finally a couple days ago we had a warmer day so I let everything else go. I checked the free oven temp setting with my wifes oven thermometer on a empty oven and it was right on.
I did 5 jet black, five signal blue, and 5 wine just to test. 400 degrees for 20 minutes. They came out perfect.
Thanks smoke and thanks to all the guys who have posted information here which made it easy for me. Big thanks to my wife who helped and picked the coated bullets out of the BBs with tweezers since I'm a little shaky.
