Marcy QC4 Universal Rain Sensor Lens Gel Kit – 2-Part Auto Windshield Gel, Fast Cure, 4ml Replacement for Rain Sensor Lens Installation (Bracket Required)

The Marcy QC4 Universal Rain Sensor Lens Gel Kit is a professional-grade, two-part gel system designed for the replacement and reinstallation of rain sensor lenses on automotive windshields. This 4ml kit is formulated for certified use and provides a secure, transparent bond between the rain sensor lens and the windshield, ensuring proper functionality of the rain sensor system.

This kit is not intended to hold the rain sensor itself to the windshield — the sensor bracket or mount must already be attached to the glass. If the bracket is not in place, it must be reinstalled prior to using this product. The QC4 kit is specifically designed for lens replacement only, making it ideal for professional auto glass technicians handling sensor reinstallation after windshield replacement.

The Marcy QC4 gel cures in under 4 minutes at 70°F (21°C), enabling fast turnaround times for installations. While the gel is universal in many applications, it is not compatible with all vehicle models. Please review compatibility notes and ensure that the rain sensor bracket is properly mounted before use.
