Mikronite

[Bobbyhotrods@comcast.net]

January Car Craft has an article on Mikronite (Eatontown, NJ) surface treatment 
of a ring and pinion. While it's proprietary, the technique uses high pressure 
blasting with some sort of media like walnut shells. The process results in a 
harder, brightly polished surface that was good for 6-8 rear wheel h.p. in a 
couple of dyno tests on street Mustangs, not bad for a $200 outlay.
