Rusty rotors- need help!

Mike

PC is ok, I mean, I am a professional powdercoater, but I still use spray paint on my own. I have also ceramic coated them in the past. Any of the 3 coatings will burn off on track use. For the street all 3 will hold up. My order of preference is Ceramic, Paint, Powdercoat. The ceramic is kind of a pain to set up, clean up and apply, so I only did it one time and it still burned off at the track. The spray paint doesn't require masking, as its a thin enough coating to let the brake pads scrape it off, and it doesn't peel when properly applied.

I do charge 25 per rotor to PC the centers, but you have to mask off the swept area and can't get in between the cooling vanes. By masking, you don't get a nice clean edge where the pads and rotors meet.

Now, all that being said, depending on how early UPS delivers my new rotors today, they may actually get powdercoated instead of spray painted, as they will be my street rotors.

my centric rotors came in today and have a nice shiny black paint on them. We will see how they hold up.

use CLR? or just spray a little wd40 on a cloth and rub it off.. from your standpoint of selling the car it would probably be better if they were just really clean than spray painted...

Factory nickel-plating is the only finish I've seen hold up to all conditions.

Do you just spray the entire rotor then? From what you say, it doesn't sound like you mask the pad contact area at all.

I'd considered painting my rotors with a couple of coats of high temp engine paint in the past but worried about masking the swept area.

ChrisSlicks

On the rotors for my truck I did 3 coats of caliper paint, 2 light coats 10 minutes apart followed by a wet coat. It's best if you cant let the paint cure a few days before reinstalling, but masking isn't necessary as it wears off quickly with some gentle braking. I would also recommend a light coat of caliper grease on the top of the rotor hat where it meets the wheel to prevent sticking.

Mike

Yep, no masking at all
