Washed the R with this stuff. Worked well and the car had a lot of really greasy dirt on it. Tried the Turtle Wax Ceramic Wet Wax. Had my doubts, and have not seen the car in the sun yet, but this stuff seems to be the shit. I did use the Turtle Wax Ceramic Spray Coating a few months ago and have not washed it since. Can't set a bone dry mc towel on it as it will slide off a not totally flat surface.
And all made in the USA. Very inexpensive too.
