3M 7000045748 Lightweight Body Filler 1 Gallon 2-component

Product Description

The 3M 7000045748 is a 2-component lightweight body filler designed for automotive body repair applications. Sold in a 1-gallon package, this filler is mixed with a hardener component to initiate a chemical cure, producing a rigid, sandable repair surface. It is used to fill dents, dings, low spots, and surface imperfections in vehicle body panels before priming and painting. Auto body technicians and collision repair professionals apply this product as part of a standard body work sequence. At 8.8 pounds per unit, the gallon container provides enough material for multiple repair jobs.

This filler is applied in automotive body shops and collision repair facilities handling passenger vehicles, light trucks, and fleet vehicles. It fits into the standard two-step mix-and-apply process common in production and refinish environments. The product is sold in single-unit quantities, making it practical for both shop stock and job-specific purchasing. Technicians working on panel replacement, rust repair, or dent correction will find this format suitable for moderate to high-volume repair work.

Installation Notes

Application should be performed by a trained auto body technician following proper mixing ratios for the filler and hardener components. Work in a well-ventilated area and wear appropriate personal protective equipment including gloves and a respirator rated for chemical vapors. Do not apply over wax, oil, or contaminated surfaces — prep the substrate by sanding and cleaning before spreading. Allow full cure before block sanding, priming, or applying topcoats.
