3M 7100166595 Waterbased Rubberized Undercoating 18.5 Fl Oz

Product Description

The 3M 7100166595 is a water-based, rubberized undercoating formulated for automotive corrosion protection and noise dampening. It applies as a paintable coating that bonds to metal surfaces on undercarriages, door skins, wheel wells, trunks, and floor pans. The formula meets low-VOC requirements applicable in most states, making it compliant for shop use in regulated markets. This product is designed for professional auto body technicians and collision repair shops that require a clean, ready-to-apply undercoating solution without solvent-based cleanup demands.

This undercoating is intended for automotive applications where corrosion resistance and sound deadening are priorities. Typical use cases include refinishing undercarriages during collision repair, treating exposed metal in wheel wells after rust remediation, and protecting floor pans and trunk interiors. The water-based formula keeps VOC output low, which is particularly relevant for shops in California and other states with strict air quality regulations. It is applied using the 3M No Cleanup Applicator Gun 08801.

Installation Notes

Application is typically performed by auto body technicians or undercoating specialists using the designated applicator gun. Before applying, ensure the substrate is clean, dry, and free of loose rust, grease, and debris. Shake or agitate the container as directed before use, and work in a ventilated area even with a low-VOC product. Allow full cure time before exposing the treated surface to moisture or applying topcoats.
