I generally sand-blast mine,but if you scuff them up real good it will let the paint stick.I also keep an old set of forks to mount them in and spin them as I spray to give them an even coat.However if you do this make sure that it is not a windy day with your wifes new car in the area. It takes 3HRS. to get rat rod orange overspray off the front of a car with a clay bar. Trust Me. lol
