it is 5% on rears and 20% fronts, my buddy did it, he owns his own tinting business and used the best stuff he had, i love it ...... im considering going with 5 on fronts tho cuz you can still see in the car daytime.... my friend has 1.5% rears and 5 fronts on his white protoge.... its sweet, tint actually does a lot for a car makes it look sportier imo. but you do get tickets for it.... a lot cops are always looking for this crap.... where i live at least
