Planning on doing 35% on the front windows of my Canyon. We did the darker 25% tint on the rear and 35% on the front windows of my wife's car, it looks fine and makes it easier to see out at night. The car had no tint at all, it stays much cooler in the hot sun.
Good quality ceramic tint lasts. My wife's car is 10 years old now and the windows all still look like the day the tint was installed. That is pretty awesome, because the UV here in thin air land Colorado is intense.
