I painted mine with Bill Hirsch cast iron gray paint, and it looks as good today as when I did it 4 years ago. The trick is to make sure that the casting is clean and oil free. I washed mine down with brake cleaner, and then brushed on the paint. It flowed out to a smooth brushless finish. Looks just like fresh cast iron. I used his engine enamel, chassis paint, miracle paint, and high temp paint, and found them to be the best that you can buy. More expensive than the box store paints, but these work.
