I had always wanted to build a motor with the old briggs copper color that was popular in the 70's. On the 'oldminibikes' forum, I heard about the Rustoleum High Temp Ultra 'Aged Copper' paint. I tried it and this is the result. The paint was thin and required several thin coats to make it turn out. It would run very easily if you got too much. I think the color is a good match for the 70's paint.
