I gotta tell y'all, just from personal experience, soap has not been just soap----I have used stuff that makes the car look like Steve Buscemi's ass when its done---that aint good...since switching to Gliptone Wash N Glow, I have seen dramatic results in difference...the San Marino Red paint seems to come alive and look awesome when Im done with the Gliptone treatment---the other soaps I have used never got the car to the same level of shine to be honest.
