Well, I had this problem too. There is a thick rubber like coating on them. I tried different kinds of stripper and nothing worked. So, I taped the area around them and carefully scraped all of the coating off with a new razor blade. Its quite a PITA but well worth it. The trim is very soft metal and you will nick it up a bit. After I removed as much as I could, I sanded with 400 grit sandpaper. Then I sprayed a coat of etching primer, Then two light coats of sandable primer, sanded smooth with 600 grit. Then two light coats of semi gloss black paint. I finished of with light sanding with 2000 Grit to get the dust out and take the shine down some. Applied some trim dressing, Much better now.
