ok so i got my windows tinted yesterday and i was the happiest guy in the world until i noticed sumthing wierd... my dad accidently rolled down the window today and i noticed that about an inch off the top of the glass has no tint. i looked around outside my car and noticed that all my windows have sum gap of tint and then just my regular windows. i didnt dare wind down the windows to check even further but i KNOW there is about an inch gap. is this normal? i hope i didnt get taken for my money or else tomorrow im heading right down back to that shop....
