3M Lightweight Body Filler repairs dents, dings, and other cosmetic imperfections on bare steel, aluminum and fiberglass reinforced polyester (FRP). Our automotive body filler may also be used on many industrial and architectural surfaces needing cosmetic repairs. 3M Lightweight Body Filler comes in a creamy formula that is easy to mix, spread and sand. Manufactured with only the highest quality ingredients, our auto body filler is vacuum processed to minimize pinholes. The filler cures tack free in 20 minutes with good handling characteristics. It resists loading sandpaper, so sanding is easier and you can use less abrasives. This is a two-component product that includes both filler and cream hardener.
