Painting Rotors to Prevent Rust

[TheBRZsKnees]

After a couple months, the front rotors on my RR Racing Sport kit are looking pretty nasty where the brake pads don't touch.



Does anyone have experience painting roters to prevent this? I'm seeing recommendations VHT Caliper Paint on various sites. I'm not sure if I need primer in this case. There are a couple VHT primers like this one, but I'm not sure which would be best.

I know I should mask off the area where the pad touches the rotor to prevent the paint from contaminating the pads. Is there anything else to be on the lookout for?

Leave it, it matches your wheel spacer.

Haha, well played.

Prep is key too it lasting and not chipping. Sand off all the rust, alcholol clean off area. High heat primer,color, clear. Make its the 1000 degree plus paint since rotors can get very hot. I wouldn't worry about masking as driving and braking will take off any excess paint

Is clear coat necessary to protect the paint, or is it just for aesthetics? Can it be skipped if I don't care about a gloss finish?

Clear coat is not high temp. I would use brake cleaner to clean the brakes. I also would tape off areas you do not want painted. Unless you want paint in your slots....

It seems like the potential products here are brake cleaner, primer, paint, and clear coat. I see tutorials where people use only brake cleaner and caliper paint. Can primer and clear coat be skipped for this application?

Yes. Clean the shit out of the parts. Tape them off. Spray a couple coats of high temp paint. Primer and clear are unnecessary.


Do not touch them till they are dry. 24 hours should work if your parts stay at least 60 degrees F.

Next time you can buy rotors that come with the coating in the first place

disagree Ive done the just paint color on method and it will chip off. The primer is to grip to the iron/metal.


And there is high heat clear coat, not too look glossy but to protect the color coat. The amount of nasty particles, road salt, brake dust can eat through the paint.


What I said is important if you want it to last. If you want to skip steps and do it quick you will be doing it again next year.


Saying from old guy at work : "If you don't have the time to do it right when will you have the time to redo it"

Show me some 900 degree primer. I used to work at a paint shop. Additionally, Hi temp paint is like enamel, and does not need clear coat.

That is clear; not primer.
