I have used it several times. I guess it works pretty well but it isn't anything earth shattering. It goes on and off pretty easy with not too much effort. It is a wax, so you have to be careful of any areas of trim that will get wax buildup residue. As far as lasting. I using it on my jet black BMW and when first done it looks like glass. After a few washing and drives, it looses the gloss and you start to see the fine scratches in the black paint. Maybe for other colors this isn't an issue. Then again, no wax I use on my car looks like it does after a few washes.
