Cost of tinting

He may have tried to match the other tint by going a shade or two lighter. The reason for this is that your other windows had very little factory tint but that little window comes with a darker tint preinstalled. If he used the same exact tint he used on the rest of your windows then the little under spoiler window would have came out darker than the rest of the windows. I guess he just chose wrong.

 

But it's not even the same hue. My front and back windows are different darkness but all have the same hue, more greenish than bronze.

 

He really screwed up then.

You can always go back and talk to him about it and maybe they will give you a discount on your next car or something.

 

I'll just make them take it off and fix it. I'm planning on getting a bunch of my house windows done so if they want that job - which is about 6x as much or more windows than the car - they better make me happy.
