I ended up going w/20% on the back 3 windows and im gonna get 35% on the front ones. The 35/20 is a good combination,they accent each other well, doesn't look tacky, besides, w/the back windows darker, it'll make the front ones look darker than they really are. The dude hooked me up nicely, he gave me 3M Scotchguard metallic tint, did the back window in one-piece and removed the 3rd brake light to tint that area as well. The metallic tint was supposed to be a $50 upcharge, as was the single piece back window, but we were choppin' it up for like a 1/2 hour, dude was hella cool, and I threw in there the fact that I drove from Sacramento to Stockton to get it done and he charged me $20 for the single piece back window and gave me the metallic tint for free. Llumar film, 20%, dual piece back window would have ran me $139, I paid $160 and got 3M scotchguard metallic film, 20% and single piece back window. Now when I get my car painted, the tint will closer match the paint:thumbup:
