So as we all know the Audi TT is a great car and we love them but its not without its problems so I was on the search for this solution to sort the cracked discoloured vin window and I did come across some different products but some were very expensive and some just don't last long and others the window looked very dull so I decided to have a go myself and this is what I came up with. they only take 15-20mins to install and look very oem .
