Part #: 40561

The 3M™ ULTRA LIGHTWEIGHT BODY FILLER GAL from 3M Automotive is an advanced, two-component polyester solution specifically formulated for professional technicians in automotive and industrial repair environments. This high-performance body filler is engineered to simplify the repair process, offering exceptional workability and strong adhesion to deliver durable, high-quality finishes on various substrates.

Key Features

  • Lightweight Formulation: Its ultra-lightweight composition allows for easy spreading and contributes to reduced material usage during application.
  • Superior Adhesion: Engineered to bond effectively to a wide range of surfaces, including bare steel, aluminum, SMC, and fiberglass.
  • Minimizes Pinholes: Vacuum processed to significantly reduce the occurrence of pinholes, which decreases rework and ensures a smoother final finish.
  • Effortless Sanding: Cures tack-free within 15-20 minutes and is designed to resist sandpaper loading, facilitating faster and easier sanding.
  • Creamy Consistency: Provides a smooth, creamy texture for easy mixing, spreading, and feather-edging, ensuring optimal control during application.
  • Fast Curing: Achieves a tack-free state rapidly, typically within 15 to 20 minutes, thereby optimizing repair cycle times and shop efficiency.

Applications

This 3M™ body filler is ideal for a broad spectrum of professional repair tasks, including the efficient filling of dents, dings, gouges, and other cosmetic imperfections. It is suitable for use on vehicle body panels, industrial machinery, and architectural substrates made of steel, aluminum, SMC, and fiberglass-reinforced polyester (FRP). Its ease of application and rapid-sanding characteristics make it particularly effective for both minor surface repairs and extensive panel finishing, assisting technicians in restoring original contours prior to priming and painting.
