Well 2013-2015 has had some changes in the window film industry. First was ceramic, then Nano-ceramic, NOW we have the highest heat rejecting film on the market. Carbon-Nano-Ceramic. Blocking 90+% of the Infared Rays. (how hot the sun feels on your skin) This is the clearest and most effective window film on the market. Oh yea did I mention it DOESN'T have any soluable dyes in it so NO PURPLE film! It may cost a little more but stop by and feel for yourself. What do YOU want on your vehicle?
