[Spits] Touching up black stainless steel trim

[Doug Braun]

Hello,

On my car, one of the black-finished stainless steel pieces that go over
the rear fender seams has gotten scratched, and the shiny bare metal shows
in the scratches.  Does anybody know a good way to touch up that finish?

The other unscratched piece is in perfect condition- I am surprised how
well that finish has held up over the years.

Thanks,
Doug
