Ben,We do them all the time at our shop- We just did some last week for our '23 project - I'll take a pic when I get a change.
I do not want to step on anybody's toes but I powder coat my own parts.
You can purchase the powder almost anywhere
just to not use your wife's oven
purchase another oven used during the temperature up to 400° and cook it
I hope nobody gets mad at me
BenGeorge: Sorry for the late reply-guess I missed it the first time. We don't use a special powder on the rotors. The typical polyester modified powders works great - we've never had any issue with it burning off - The rotors on my '27 were done 6 years ago and look perfect.
Don't know why anyone would get mad? Yes, there are many folks that do their own - just like they paint their own cars. If you have the time and a little equipment, its definitely doable at home.
Sound like you need an HPC coating of some type. Here's who I've used for the exhaust on my truck, but there are many such companies in the U.S. http://www.hpcoatings.co.nz/
We do this kind of ceramic coating as well. The concern with it is that it is a thermal barrier. That works well with headers where you want the heat to not be absorbed by the pipes (heat soak), but on a solid rotor, you could be trapping in the heat which would not be a good thing. I ceramic coated the brake drums on my '27, but they really don't get hot enough to worry about. A solid rotor for a road race car is different. We do have some other coatings that are thin and handle the heat, but are not ceramic. If there was a concern with the powdercoat, there are higher temp offerings that will go higher that the typical powders.
yes- you can get any sheen from High Gloss to matte.
