I have a 91 ETC which, like many Caddys or GM passenger cars for that matter, has black "B" pillars. But over the years the surfaces have become oxidized and dulled. Does anyone have any advice as to how to best refinish them? I ask because I'm not certain they were originally painted black, or whether its some special powder coating. I have considered just spray-painting them gloss black, but of course that rarely looks as good as a body shop's baked finish, if that's what they came with.
Thanks for any tips!
