Overview
Built for the job.
3M™ rocker panel coating is a resilient coating designed to protect vehicle surfaces where they are vulnerable, on rocker panels and other lower auto body panels and parts exposed to impact from gravel and stones. Formulated to match coarser OEM textures, this coating forms an extra layer over primer and under paint.…
3M 08889 Rocker Panel Coating is a gray, medium-texture aerosol formulated for rapid protection and finish on rocker panels and other exterior sheet metal. It is applied directly to bare metal, OEM surfaces, or over primer to create a durable base layer before topcoat application.
The coating is designed for a two-coat system, providing uniform coverage and excellent adhesion to the listed substrates. Its low flash point of 4 °C (Pensky-Marten) indicates rapid drying under standard shop conditions, allowing efficient turnaround in collision repair workflows.
Due to its acute toxicity, flammability, and classification as a carcinogen, appropriate personal protective equipment-including eye protection, gloves, protective clothing, and a respirator-must be used. Ensure adequate ventilation and follow H-statements H223, H229, H304, H315, H320, H333, H336, and H350 when handling.
