I bought Sonax for my freshly wrapped car as I saw some reviews of it to be a good protector for vinyl wraps. AND it IS. My car is wrapped in matte and gloss vinyl, it is my rolling business card since wrapping stuff is my business. Beading is great, it doesn't change the matte vinyl in its appearance but rather enhances its color. No streaks, nothing. Dust and dirt go easy of and bug splashes don't leave any marks.
I am recommending it also to my clients and I actually like the smell (kinda Pinacolada :))
To me it looks as good as expensive nano protect for a bargain price.
Good stuff...hope you will get the "Vinyl Detailer" from Sonax, which is right now just available in Germany. I would LOVE to try that.
