You'd have to polish them alot. I wouldn't say they were polished but I brought a set of s4 na rotors to about a 600grit finish and when I pulled the eng apart it hadn't made any difference in carbon build up.

If lower oil temperatures is what you're after you're going to see far better results with coatings. We also offer the balancing service.
Or, you could just set the car up right and the money spent on this coating junk won't be wasted.

Easy there B. The "right" set up may be different depending on who you talk to. Also; last I looked, keeping as much heat in the combustion chamber and in the exhaust was a good thing.... At least on the side of turbo spool characteristics.
As far as I understand, the rotor faces communicate a lot of heat into the oil (as they are full of it) But again I am assuming. I merely like to ask these questions so there is more info out there. I am a novice engine builder(with rotaries anyway), but I love learning everything I can.
Peace, love, and chicken grease

I agree on the turbine housing and turbo/exhaust component portion, but I'm nowhere near sold on the idea of coating the rotor housings, iron housings, rotors, etc. I think it's a bad idea. I've seen engines fail showing problems with internal coatings.
