Well i dropped my car off @ a shop on Thursday and they were supposed to change all my fluids and a few other things. so i get it back today (Tuesday) and i saw my newly powder coated CTS-V Calipers were not shiny red and looked wet so when i went to clean them the powder coating rubbed off !!!! i dont know what to do im not even in that town any more. what should i do let it dry or take off the rims and clean them off w/ the paint ? anything i can do ?

Usually powdercoat is resistant to brake fluid...but seeing as you had them done recently, the powdercoat probably wasn't totally cured, which is why it came off when they flushed the brake fluid (which is what they did I'm assuming).

I would just let them dry, clean them off with some Simple Green (to remove the brake fluid residue) and see if you can have them re-coated. That really sucks though, I'm sure they looked nice

If it is coming off, you'll probably need to have them stripped and re-powdered. Talk to SilverGhost (Sean Falls) - he's a sponsor on here that does very good powder coating work, so he should be able to tell you what your options are.

More than likely they need to be stripped and re-coated

Its not a curing issue as mentioned above. Powder is ready to be put into service as soon as it cools off after curing. Some powders will continue to fully harden for up to 24 hours but that won't affect chemical resistance, just impact resistance.

Sounds like the brake fluid sat there for a long time, which can eat powder eventually. Short exposure of brake fluid will not cause that probem with properly done powder coating.

Its possible the coater is partly to blame as well in their prep work, mil thickness, and cure schedule. However even the best work can get ruined if that very corrosive brake fluid sat on the powder long enough.

I'd be glad to help you get them back into shape, feel free to PM me or call 847-561-4361.
