I tinted my c240 1 1/2 months ago and the window is completely scratched. Everytime you roll the windows up and down it gets worst. I took it to Best Window Tinting in Tustin, California. I will be calling them and demanding a refund of the $180 I paid them. Flecther Jones Motor Cars used them in the past but the dealer completely stopped tinting cars for the customers becasue of all the headache it caused. The tint shop used Solar Gard window tint, which I believe to be the problem, it seems like it sucks and gets scratched to easly.<p>Does anybody else have this problem?<p>I will let everyone know the outcome, but don't take your cars to Best Window Tinting!
