installed meth injection two months ago and been using washer fluid..kit is great and love the results till today when i removed my intercooler...come to find that all the coating is gone from the sc rotors..i got the shiniest rotors ever and not happy...anyone else ever have this problem and is there a way to stop it minus injecting below the sc as i can install new rotors but dont feel like just making another clean set..this aint no rotor washing factory
