Bought some of this in December. It's yet another wash and wax product but, in my experience, this actually works. You use quite a lot - 3 fluid ounces per gallon - and it doesn't foam up that much - but it definitely leaves a significant coating behind.
You rinse the car with a hose then wash the car as normal with a wash mitt or similar. It tends to soak the surface - ie it doesn't seem to bead. When you come to rinse off then - wow! The water beads like crazy. You can then wet dry the car using a gentle flow from the hose and the water just slides off. Finish off with a microfibre towel and your car looks as if it just been waxed.
I'm aware this sounds like an advert but I've been blown away with this stuff.
