When i bought the car it apparently had louvers but they were removed....I didnt notice it had scratches till i put tinted windows today....Is there a way to remove the marks....it has the marks of where it use to go

 

Eastwood makes a glass polish, but I've never used it to know how well it works. I have heard that you need to be careful when using it or you can warp the glass, but if used correctly it does a very good job of removing scratches.
