I went today and scheduled my tint job. I decided that i wanted to go with 20% all around. I was just wondering if that is too dark. I don't wanna have problems at night. I got 5% on my explorer on the back windows and had alot of trouble at night. Should I have gone with 35%? I have alittle time to change my mind before next thursday. I know the back window can be trouble if i decide to remove it. I would appreciate you input.

Thanks
