Screwed up with my tint. I used to have 50 percent on my windshield which did look good, but at night i was having some problems when i drive through unlit areas. You never know if you are even about to hit a deer or not, so i took it offThen on the rest of the car i had 20 all around. I wanted the rear to be a little darker. So i put another layer of 20 over my existing tint. Now its almost impossible to see out of the rear windshield but it does look pretty cool. What i should of done was went with a layer of 35 over the 20 which would of given me about 7 percent tint, now i have somewhere around 4. Long story short, i think im going to try it for a few weeks, if i dont like im going to have to remove the tint on the rear windshield and start over ughhh. Plus side is that i can see my Special edition seats now through the front. Before my car looked pretty dark.
