Only original, unaltered and unmodified materials and workmanship are covered by this policy and you must provide proof of original purchase to be fully covered. This warranty does not cover damage caused by accidents, improper care/installation, negligence, reasonable/normal wear and tear, or the natural breakdown of colors, coatings and materials over extended time and usage.
