Back in July, I slid a little in a muddy creek bed and bruised the silver wing on my rear bumper (left side). I wasn't too concerned, but thought I'd just paint both silver end caps with black bumper paint. I used a 2 step system where after thoroughly cleaning the bumper ends (and masking around the area), I applied an "adhesion promoter" and then used as black bumper paint. I am quite pleased with the results. I wouldn't nessecarily do this on a TiSilver or Black, 'cause the silver adds to the appearance on those color schemes, but IMHO, the silver on the black and yellow is a little incongruous. Anyway, the results are below:
