I used Wearmax in several spots some that are really bad. It worked amazing. It was clear but it took the white mark away !! I went back to it a few days later and tried to rub it off and it stayed. I beleive this will last a long time if not permanent. On deep scratches you cannot take away how deep it is but you can improve it drastically with Wearmax. I received this product complimentary in exchange for my unbiased review and opinion.
