I think I might have read it some where but can't find it, anyway I just detailed a royal blue 1987 535i (original paint) and used SSR 2.5 for the first time(for a full detail) and used a little less than 1/3 of a bottle. I went over the car twice with SSR 2.5. For those of you who use SSR's am I using too much. The car turned out beautiful, and there was no need to finish with SSR 1 as the 2.5 polished to a clear shine. Sorry no pics I didn't have time
