The Dynatron Dyna-Glass Fiberglass Reinforced Filler is twice as strong as any regular body filler. This polyester filler contains short strand fiberglass that is perfect for waterproof repairs. The short strand fiberglass filler is used on metal surfaces, specifically rusted-out holes and shattered fiberglass parts. 

The short strands of this fiberglass filler make it convenient to shape and spread when working on vertical repairs too. The efficiency of this product is mainly because of its thicker consistency, shorter strands and fibers. The short strands help smooth surfaces even better and they can be pushed easily into surface imperfections.

The Dynatron Dyna-Glass Fiberglass Reinforced Filler is compatible with all paint and conceals repairs. This keeps the repair completely hidden from sight and helps you restore your car back to its old glory. This product includes hardener.
