I have a tub of it.. bought it because I was curious to know how well it cleans, and whether it would remove any swirling or other light defects, as well as durability.
My conclusions? It didn't seem to make any impact at all as far as swirls, but it did do a decent job removing some light haze. Initial shine, water repellency, and slickness were okay, but it seemed to wear VERY fast.
All in all, I wouldn't consider it great.. if you have some slightly hazy paint, maybe some water spots that won't wash off.. then it should work to clean that up, but on paint that is otherwise shiny, I would go with something that is a dedicated wax or sealant, like Meg's Gold Class, NXT 2.0, or Ultimate Wax, etc..
