This amazing material from Percy's is just the ticket for windshields, side and rear windows. Not to be confused with the more economical plexi-glass, this material allows anyone to cut to fit with common hand tools, but its special coating is scratch and chemical resistant. This surface hardened plastic is similar to Lexan, but can be cleaned like normal glass without scratching. You can even use windshield wipers on it and clean it with standard glass cleaners.
