The 3M 7100171795 is a dedicated applicator gun designed for spraying rubberized undercoating and rust-inhibiting products in automotive and fleet service environments. The gun provides a controlled, consistent spray pattern for viscous coatings that standard spray equipment handles poorly. Weighing 0.73 pounds, it is lightweight enough for extended overhead or awkward-angle application. Body shop technicians, fleet maintenance crews, and detailing professionals use this tool to apply sound-deadening and corrosion-protection coatings to wheel wells, rocker panels, and underbody surfaces efficiently and without mess.
This applicator is intended for use with aerosol or cartridge-format undercoating and rustproofing products in professional auto body and fleet maintenance shops. It is well suited for production-volume work where technicians need to apply coating repeatedly without hand fatigue from manipulating individual aerosol cans. The ergonomic trigger mechanism gives the operator consistent flow control across multiple applications in a single session.
Designed for use with 3M Rubberized Body Schutz (08864), 3M Rocker Schutz (08874), and 3M Rust Fighter-I (08991) undercoating and rustproofing products.
This tool is typically used by auto body technicians and fleet maintenance professionals. Before applying any undercoating product, ensure the vehicle surface is clean, dry, and free of loose rust or debris. Follow all product-specific ventilation requirements when working in enclosed spaces. Refer to the coating manufacturer instructions for proper application distance and coverage rate.
