Dynatron™ Ultra-Glass™ Milled Glass
Greater Strength than Ordinary Filler
Dynatron™ Ultra-Glass™ reinforced filler is designed to be used as a reinforcement material during the repair of holes, cracks, or tears in metal and fiberglass panels. 3M™ Dynatron™ Ultra-Glass™ offers excellent sag resistance, high build, and gap spanning characteristics when repairing or filling larger gaps in auto body, marine, industrial and architectural surfaces. Dynatron™ Ultra-Glass™ is a two-part polyester filler that is reinforced with milled fiberglass to create a waterproof repair. Our milled glass filler is stronger than ordinary body fillers and may be used in conjunction with fiberglass tape, cloth or matting to repair and rebuild rusted out metal and damaged fiberglass and wood materials.
