Expect to pay anyway from 90-120

The place I go to uses llumar tint with a lifetime warranty, depending on where you are located there are various good shops that will do your tint correct...

The place I go used only 1 piece of tint to do my whole back window.. some places ad 2 layers which looks tacky.. I have 5% tint and I can see perfect during the day and its not too bad @ night
