3M 7100046055 Rubberized Undercoating 16 Oz

Product Description

The 3M 7100046055 is a professional-grade rubberized undercoating supplied in a 16 oz aerosol format. It applies as a black protective coating that stays in place without running or sagging after application. Designed for use on metal underbody surfaces, it delivers anti-corrosive protection, sound deadening, and thermal insulation in a single treatment. Licensed automotive technicians and body shop professionals rely on this product to protect underbody panels, wheel wells, and frame sections on cars, trucks, and recreational vehicles. The coating bonds to metal and cured finishes to create a durable rubberized barrier against moisture, road debris, and road noise.

This undercoating is suited for use on passenger cars, light-duty trucks, and recreational vehicles where underbody corrosion protection and noise reduction are priorities. It is commonly applied during new builds, restorations, or maintenance service when underbody panels are accessible. The aerosol delivery makes it practical for spot applications on wheel wells, floor pans, and frame rails without requiring spray equipment.
