I use a good enamel spray paint to fix the bead area of truck rims at work......... Just be sure to give it enough time to dry before slappin the caps back on....... The kitchen appliance paint works really well, as 007jimmy suggested.... the mine is just too cheap to pay the 4 dollars for 1 can....... If you want them to look really nice, take a wire wheel on a grinder to them..... It'll smooth out a lot of blemishes that are waiting to show in the new paint, and it'll make the paint adhere really well....
