You know I was thinking the same thing the other day...After trying a lot of other manufacturers rinseless washes and waxes and sealants and QDs and glazes and so on...I found myself admiring my car after a simple ONR wash and opti-seal application. The car was clean and really reflective from the opti-seal that I started saying to myself "Whats the point in buying anything other than OPT?"...and I really cant find an answer!
Im loving every second I use OPT products. And I believe this is a similar feeling for a lot of us here on this forum
