There are covers that go over the stock moldings, but I heard they don't look right.
Dugan Racing "remanufactures" them with epoxy or somthing, but they want $300 on a trade basis. I went to a body shop supply store and have some rubber/trim primer and trim paint. The primer fills in the holes and smoothes it out, and paint will bring it back with the assistance of sanding, ect. Haven't tried it yet.
