i was trying to show this to you on irc
Video - SEMA 2006 - Crane Cams interview with StreetFire.net on new Mikronite metal finishing process.
if you get some oem parts to just repair it you could look into that surface treatment, it owns the shit out of shot peening. The ring gear on the table in the beginning of the vid was in a 525hp T/A running a 200 shot and made over 40 passes. Never threw any teeth and looks brand new as you can see. They were oem components just treated with this micro crap
