Jim Bailey use to own "Finished", which did cryo & micro-polishing/surface treatment, but he sold it to someone out west. I believe there are benefits to it if it's done right. The Mopar 8 3/4 gears I run need to be watched so every little bit helps.

The guy who sets up my differentials had me bring the R&P in to set up, THEN sent it off to have it treated because the polishing makes it more difficult to "read" the pattern while setting it up.

Couldn't hurt to de-burr the edges of the teeth lightly with a sandpaper roll to eliiminate any sharp edges either way.
