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.
I think they are painted. it's a low gloss to begin with so it starts getting that chalky look to it. Is that what you're talking about.
I will tell you what I just discovered. On my DTS the grill is also black and I can't really tell weather it's paint or black plastic or what but yesterday when I was detailing the car I wiped it with my tire shine stuff and actually cleaned all that chalky crap off of it. I never knew my grill looked so cool.
Yeah, chalky is a good description. And yes, several types of detailing agents will temporarily make the surface look better -- but mine are really beyond cleaning and sealing, since they have also accumulated some scratches. I recently had the car repainted so now the B pillars really seem to stand out.
"Anodized" may be the way these surfaces were originally coated. It seems like the same process used for the black hood reveal molding the windshield wipers rest on.
