Has anyone had any experience with Croyogenic Processing Isotropic Superfinishing? This is a process that cools parts to change their properties and then use a finishing process to make them less prone to friction. The site for Evans Performance Products, which does this process, is

I was thinking about having my transmission (915 Carrera) polished and treated to improve shifting and improve longevity. They say their process is $650 for all of the gears and internal parts. If this helps shifting and improves syncro wear it may be worth it.
