5G OVERSPRAY MASKING LIQUID DRY - 3M Automotive

The 3M Automotive 5G Overspray Masking Liquid Dry (Model 6851) is a professional-grade, water-based sprayable masking liquid engineered to protect vehicle surfaces during automotive painting and priming processes. It dries to a clear, non-tacky film that effectively guards against paint and primer overspray while simultaneously trapping dust and dirt. This innovative solution helps streamline masking operations and contributes to cleaner, more efficient paint jobs.

Key Features

• Rapid Drying Formula: Dries to a clear, non-tacky film in as little as 20-30 minutes at optimal conditions, allowing for faster workflow in professional autobody environments.
• Comprehensive Overspray Protection: Forms a protective barrier against automotive primer, sealer, base color, and clear coat overspray, compatible with both solvent and water-based paint systems.
• Eliminates Film Flutter: Adheres lightly to vehicle surfaces, preventing the film flutter common with traditional masking materials that can compromise paint finish quality in paint booths.
• Easy Application & Cleanup: Applies readily with conventional spray equipment (1.8-2.2mm fluid tip, 30-40 psi spray pressure) and dissolves easily with water for swift and efficient cleanup after painting.
• Traps Dust and Dirt: The dried film actively traps airborne dust and dirt, preventing contamination of the repair area and promoting a cleaner paint environment.
• Enhanced Mobility: The clear film allows for vehicle mobility within the shop after application, adding versatility to automotive body operations.

Applications

This masking liquid is ideal for bulk masking of vehicle surfaces in professional body and paint bays during priming and painting. It is particularly effective for protecting hard-to-mask areas and can be applied to thoroughly cured painted automotive body surfaces, metal, and tires in good condition. The 3M Overspray Masking Liquid Dry helps protect components such as engine parts, provided the engine is cool during application and the masking liquid is thoroughly removed before starting the engine. This product is designed to protect against overspray, not direct paint hits, and should not be used on old oxidized paint, fabric tops, lacquer paints, or freshly painted surfaces (less than 30 days old).
