I have to say that is one of the few I have not played with. I have used all of meguiars other products. I can say though fairly confidently that none of those products need dwell time. The cleaner and polish can be worked in and buffed off. Carnauba wax can always be removed immediately. Some carnaubas can become difficult to remove once all the solvents have evaporated. Also, I won't knock meguiars. I sell some Meguiars products. I used their professional line and 3M in all my dealer staffed sites. For an autoparts store Meguiars and 3M are probably the highest quality you will find but still a step below a Klasse, P21S, Poorboy's, Menzerna etc. in my opinion.
