Anyone familiar with the stuff? The dealer is claiming it will be invisible and will prevent paint chips from road debris. It is thicker than just a paint sealer and just goes on "leading edges" of the car like front grill to emblem and back of side mirrors. It supposedly does not have UV blockers so the paint will stay the same color over time. Costs $600. I live in Vermont where road salt and sand is definitely an issue in the winter, so I am attracted by its protective possibilites but don't want to ruin the look. Can anyone help? Thanks.
