I painted my calipers using Duplicolor brake kit from walmart. Comes with 1 can of brake cleaner, paint, and a brush. I put a good 3 coats on and it turned out nice! Just get some sand paper and sand off any rust or rough edges. You might be better off spraying drums with a high temp paint.Ok, who has painted their drums & calipers? What kind of paint did you use and did you have to get the rust off them first?
