I haven't seen any tint that will match OEM tint. OEM tint is in the glass itself. Completely different process. I wish the OEMs wouldn't tint any glass. I would rather tint all the glass and have it match. I tinted all my windows 15% except the windsheild. The rears are nice and dark. The fronts are about just right. I think it is Sun Gard tint. HD or performance series. I can't remember. 3M film is supposed to be the best. Lastly, alot rides on the quality of the install. Find an installer who has been at it a while and likes what he/she does. Also, see what kind of vehicles roll through the shop. If all you see are a bunch of ghetto rides then that will likely be about the same level of quality of tint you will be getting. If you see all high end rides and the customers are happy then that shop will likely have better installers and better film.
