So I'm going to be getting a rebiuld soon and I need to know about WPC. It sounds great, but I haven't heard of any rotories with it. I tried the search, but it seems that no one else has heard of the out come of it on a rotoy. Please educate me if you have any info of it on a rotoy motor.

Here is the link for those who don't know what I'm talking about: www.wpctreatment.com

 

it simply adds minor dimples to the metal surfaces.

In a rotary, the only advantage would be in the housing or plates, but I would suspect that there would be minor increase in apex seal wear due to wpc treatment on the housings.

You would probably get better results if you want to lower friction with having the housings and plates cermat coated instead.
