I had my windshield repaired for the previous 350 just before I return it to the dealer. They use the Novus windshield repair technology by injecting a specially formulated resin into the damaged area. The resin is then cured and polished to restore structural strength and clarity to the glass. The result is very good and the repair is very hard to notice unless you know it is there. The earlier you do it, the better the result. More infor and locations ->
