Good evening...looking at purchasing a used Jetta GLI and it appears that it drove through a sand storm on a few occasions. I am confident I can make the paint look acceptable with my Porter Cable but the headlights concern me. This is a 2016 model and they are clear, but when you run your nail or hand along the headlights you can feel the dings in the plastic. Can a professional wet sand them to the point where they are eliminated generally? Ballpark how much does this generally run? Thx
