For those who have vinyl in your car, what products have you been using to keep it shiny and staying original colour? Mines seems to be fading, wether its the shampoo im using or doing something wrong. Up close theres like black smudges all over. Only noticeable up close, but it looks as if... it was black originally, and the green is fading. Also tar build up, cant clay vinyl?
Need some tips, its losing its lovely green colour
