3M 7000125048 Dyna-glass Short Strand Body Filler 1 Qt

Product Description

The 3M 7000125048 Dyna-Glass Short Strand is a polyester body filler reinforced with short-strand fiberglass for high-strength, waterproof repairs. The fiberglass reinforcement delivers approximately twice the strength of standard body fillers, making it suitable for demanding repair and rebuild applications on rusted-out metal panels and damaged fiberglass substrates. At 3.25 pounds per quart unit, it is packaged for professional shop use. Body shop technicians and composite repair specialists reach for this product when a conventional filler lacks the structural integrity the job requires.

Dyna-Glass Short Strand is used in automotive body repair, marine repair, and general fiberglass fabrication environments. It works on rusted-out metal that has been cut back and prepped, as well as on cracked or damaged fiberglass panels. It can be applied in conjunction with fiberglass tape, fiberglass cloth, or fiberglass mat to bridge larger voids or reinforce weakened areas before finish work begins. Typical users include automotive body technicians, marine repair technicians, and RV repair shops handling both metal and composite panels.

Compatibility

Installation Notes

Application is typically performed by automotive body technicians or composite repair professionals in a ventilated shop environment. Mix only the quantity needed per manufacturer mixing ratio instructions, as pot life is limited once the hardener is introduced. Surface must be clean, dry, and properly abraded before filler is applied. Follow applicable safety guidelines for polyester resin products, including use of appropriate PPE for skin and respiratory protection.
