: whip out the rattle cans; no FNC rotor treatment for V owners

This may belong in the new's section.. but I felt it was in relation to the CTS-V. Excuse the error if not.

WARREN, MICHIGAN There may be nothing worse for the enthusiast than returning from a trip to find rusty brake rotors peeking out from under fancy wheels after just a couple of days in the airport parking lot. General Motors has a solution, and has applied for patents for its Ferritic Nitro-Carburizing (FNC) process, first used on the 2008 Cadillac DTS.

FNC bakes the rotors at 560 degrees for 24 hours in a nitrogen-rich atmosphere, which applies a coating 10 microns thick, equal to one-tenth the thickness of a human hair. GM says this doubles rotor life from an average of 40,000 miles, to 80,000 miles and saves a customer up to $400 over 10 years. Meanwhile, the iron brake rotors retain their steely color underneath those thin-spoked 20-inch wheels becoming increasingly common.

GM launched the process, via its rotor suppliers, on the 2008 Cadillac DTS and has since lowered the cost of the process. There will be no extra cost to consumers, GM says. The rotors are now used on the Buick LaCrosse and Regal, Chevrolet Malibu, Impala and Volt. The automaker expects to have the process applied to rotors on 80 percent of its cars and trucks built in the U.S. and Canada by 2016.

The other 20 percent include V-Series Cadillacs and Corvettes, because of the brake lining materials they use. GM says the FNC-treated rotors are appropriate for the U.S. and Canada, and China. There are no current plans for other markets.

short and sweet; no rust-free rotors for Corvette or V owners, I suppose I'll have to spray them this weekend then..

I'll rust over a compromised rotor under extreme conditions anyday.

GM says service life is doubled because of the process in it's normal rotors, I would assume the higher amounts of carbon in performance rotors or the aluminum hat front rotors the V2 uses does not work well with the process.
