I agree with you completely. I used to wash my cars with Dawn or just pay the few bucks for a car wash to do it. I just didn't know any better.
Since I bought this car, it opened a whole new world of detailing
Hours and hours of research, about 1500 dollars of detailing equipment including a Flex orbital, etc.
I was absolutely stunned after I clayed the car the first time. Smoother than any glass I've felt.
