3M Marine Lightweight Body Filler fixes gouges, dings, dents and other cosmetic defects on fiberglass reinforced polyester, aluminum, and bare steel. This two part filler is easy to mix, spreads evenly, dries quickly, sands well, and is not prone to pinholing.

Filler cures to a tack-free consistency in 15-20 minutes; wait approximately 45 minutes after sanding to apply primer and paint. Available in a 1 gallon can.

When mixing filler and hardener, use an appropriate mixing board, as using cardboard can cause contamination. Mixing boards and 3M Marine Blue Creme Hardener are sold separately.
