well if you look in the long run with ppg you can get a paint code from the manufacture and if you get in a accident it would be easier to repair but if your not worried about it HOK is awsome but there about the same quality just HOK has there own colors where as ppg has oem colors and there own seperate custom color line as well known as ppg vibrance line but the colors start out pretty high like around 1000-2000 a gallon very pricey but awsome effects
