maybe look into getting it wrapped?
i should take pictures of my hood and the area around work here. highway construction for 2+ years now...in our backyard here. cars covered in dust nearly everyday. big trucks, graders, bulldozers, semi's etc all around, everyday. it's done a number on my hood and bumper.Where you drive and how you drive is what matters an one really effective thing you can do at no cost to you. Drive on clean roads and around clean environments and keeping some good distance between you and big trucks are just a couple ways you can make changes.
Some people pass by construction sites every day and just don't factor in the damage it could be doing to their paint, yet wonder where all the damage came from.
