I have used it before and find it to be a good product for the average consumer who doesn't wash often. I doubt that there is any protection, and if there is, it's just to sheet all the water away so water marks wont etch into the paint system.
No shine or gloss is added, and there is no noticable difference between with this infomercial product and without except for the sheeting effect. (Lasts about 1-2 months)
Not even close to Zaino, Klasse, or maybe Blackfire.
