I was wowed by UWWP when using it as a waterless wash for the first time. I managed to waterless wash my entire 09 Jeep SRT8 in less than 30 mins including wheels (typically takes me 2-3 hours with 4 bucket wash). Looked spotless and cleaned well enough to bring the beading back in areas that had a film of grime. Took the dead bugs off the bumper with ease as well! I also didn't notice and marring or scratches.
I've really taken this product for granted and even gave it some negative reviews when used as a quick detailer or clay lube due to some streaking.
Note: I had no streaking when using WW towels to buff dry.
Recently I had to get something from Amazon, and I padded my order with some glass cleaning towels, the same type as the Zap cloths that AG sells. It's a wonder to me that these water-only glass cleaning towels aren't used by more people; they really do work like WOW.
