MGD-1704 Lightweight Body Filler & Finishing Putty — 0.8 U.S. Gallon (Case of 4)

Accelerate body repair workflows and achieve smooth, wave-free panel contours with MGD-1704 0.8 Gallon Lightweight Body Filler. Formulated specifically for high-production auto body technicians and custom metal fabricators, this smooth-spreading polyester filler offers the perfect balance of creamy workability, sag resistance, and ultra-easy sanding performance.

Smooth Creams-In Spreading & Pin-Hole Resistance

MGD-1704 utilizes micro-sphere filler technology and vacuum-treated polyester resins to create a velvety consistency that glides onto panels effortlessly. It fills low spots, spot welds, and panel transitions without dragging or trapping air pockets, yielding a dense, pinhole-free repair surface ready for primer surfacer.

Multi-Substrate Strong Adhesion

Engineered to bond securely across all modern automotive metals, MGD-1704 eliminates the need for multiple specialized fillers. It delivers exceptional chemical adhesion to cold-rolled steel, galvanized metals, aluminum panels, SMC, fiberglass, and sanded factory finishes without lifting, shrinking, or edge-mapping over time.

Fast Curing & Feather-Edge Sanding

Formulated with a fast-reacting cure cycle, MGD-1704 dries tack-free in 15 to 20 minutes at standard room temperature. It sands down smoothly with 80-grit to 180-grit sandpapers without clogging abrasive grains or tearing along repair borders, allowing technicians to feather edges seamlessly into bare metal.
