Thought I read some where that there was a rating on the amount of reflection or shine a spray wax puts out? May be my imagination?? Not considering durability and such, I have two of the top spray waxes IMO, but have a white car and frankly can't tell the difference. Probably could tell better on a dark color. I have Meguire's Ultimate quick wax and Souveran spray wax. Kind of nit picky but was just curious.
