Has anyone found a readily available paint that is a reasonable match to 1990's Dark Silver trim color that was used for some bumpers, fender flares and other trim? I can get it custom mixed locally to the original KS7 color code but it would be rather expensive for what I need. Immediately I want to paint the black plastic rivets used to attach the lower front air dam to the fender flares on my '91 XJ. I am looking for either aerosol or brush-on for this application.
