I have pushed onr to its limits. Its is a good maintinance wash for inbetween washs. When I first got it I would see how dirty of a car I could wash since I was doing a full correction but I still used common sense it's not going to emolsify sand. Plus it does offer a bit of a gloss enhancement. All in all its a great product like everyone has said and is a must have. You can use it for washing, QD, and even a clay lube( which will save u a ton if u clay a good amount of cars). Do yourself a favor and by the small size and give it a shot, and after that kick yourself for not buying the gallon.
