Today I was talking to someone who is rebuilding rotaries. He had mentioned a coating that a mazda racing team, or car, used on the part where the apex seal runs on... can't think of what thats called right now.... I am not sure of all the correct terminologies.....is it called the rotor housing? well anywho, if anyone knows what I am talking about with this part, apparently they used to use a ceramic coating, cosisting of other things I am not sure of, silicone? Silica? I have no clue.... The guy I talked to has been dealing with these cars for 20 years, I have been for 2 months. He was talking so fast about things I am just learning, so alot of it went straight out the other ear. ANYWAYS..... I want to know if this coating lasts, if anyone heard of it, or what the deal is. Also quickly another ??, What is a good price for a ported 13b thats rebuilt? It would have this coating I remember he said something about electolisis (sp) I believe.... Thanks..........

No clue about this mystery coating. But if you wanna know about resurfacing rotor housings, look in the tech and performance section. Heres the direct link to Scalis thread.

I heard EZ Off works like a champ. Think about how it works on a nasty oven
