So I went from Adams to Chemical Guys to this stuff. I never tried any waterless products from Adams. I also had another waterless product demo'd for me once (I removed the name). I was not impressed with it. I'm a hard sell. I liked the Adams, and honestly only switched to chemical guys to try it out. I wasn't unhappy with the Adams. I found them both to be about the same. They were great for the time. Cleaned cars with better results and less chance of swirls than turtle wax in the 80s and McGuires and Mothers in the 90s.
However, my routine now is just to use this stuff. I will never go back to washing a car. I will probably pay a really good local detailer once a year to do all the cars. Other than that, it is just this stuff about once a week. It is fast and easy, and comes out better than pretty much anything else. I will never go through the 2-3 hour ritual of cleaning a car or truck again and have it still not look as good as this stuff.
I guess if I got the truck filthy with tons of caked on hardened mud, I might break out the pressure washer, foam cannon, clean bucket, dirty bucket, grates, mit, etc, just to get the big stuff off. But as soon as I was done I would go back over the car with this stuff.
If anyone lives near me (GA/SC) and wants to try some of mine first, just let me know.
