They do make a film that goes on the outside of the windshield now that protects against rock chips like PPF. From what my installer told me, they have to replace it yearly at a cost of $400. Windshield wipers wear it down. We carry a rider on our insurance for $0 glass so I don’t really care. We have had our Ys windshield replaced once. Also, our insurance reimburses for tint so we didn’t have to pay to get it tinted again. Might check what your insurance covers. Might negate the issue of tinting if you only have to pay once.
