has anyone used Duplicolor's Shadow kit, or black chrome spray paint? my bumpers on my 80 Malibu are in pretty good shape, but the chrome is pitted. I think the black chrome look would look good and possibly help hide some of the pitting, but I know how hard it is to paint chromed steel. I was wondering about how well it would adhere and hold up, so if anyone has experience with it they would like to share, I'll appreciate it!
