The Glass Mechanix Daytona assembly windshield repair system is the very finest in the industry. The Daytona Injector Assembly is the only true independent, dual-cycle vacuum pressure system in the industry. This process ensures maximum vacuum pressure (over 22 inches at sea level) with no extra parts, hoses or messy processes. Its three-point mounting system and powerful suction cup ensure level and secure mounting on virtually any visible space on the windshield. The Sprint System is also ergonomically designed for ease of use, and can be applied using only one hand.
