Re: Painting the motor?
For paint, I would not recommend any regular rattle-can/spray-can paint on the engine. It will not withstand the heat the engine produces. I would go with either high-temperature BBQ paint from Wal-Mart or go to an auto store and get a can of engine enamel. Either of these will work perfect. The engine enamel will resist fuel and oil, the BBQ paint may or may not.
Out of all the things I've lost, I miss my mind the most.
