I bought my car from the market 2 years ago. Since I have owned this car there has been marks on the windscreen where the market put there signs ( 1 lady owner etc). Can any one tell me if there is a film on the inside of the window as no matter what i use to clean it i cannot get rid of these marks. I have tried lots of sprays and scrapping window with a stanley knife blade but with no success. So i am thinking they have removed something from the screen when they removed the stickers.
Do i need to bit the bullet and buy a new windscreen or has anyone got a solution they can share with me.
I hope someone can help
