I agree with John C's review. I used this and was thoroughly disappointed. I tested this side by side against other manufacturers spray waxes. 303 was not slick at all. I compared the beading against the other spray waxes after some slight rain and 303 had no beading. The beading looked like a surface that has no protection on it. Sheeting was lack luster as well. I think 303 missed the mark with this product.

Was very impressed with their detail spray but as far as this spray wax not so much.
It did leave a decent shine behind but as far as it being labeled as a wax there seemed to be no wax left behind on the paint. When I was done it felt as if no protection was left behind. You would usually feel some kind of slickness but there was none.
