Fibral Lite Fiberglass Filler takes the place of both short and long strand products. Its lightweight formula can be easily shaped and sanded once cured.

U-POL Fibral Lite UP0766 is a lightweight fiberglass-reinforced body filler designed for structural repairs on multiple automotive substrates. This fibrous paste formulation provides excellent adhesion to aluminum, fiberglass, polyester, primer, and steel surfaces, making it ideal for repairing rust holes, impact damage, and areas requiring structural reinforcement without excessive weight addition.

The product's fiber-reinforced composition delivers superior strength and flexibility compared to standard body fillers, reducing the risk of cracking in high-stress areas. Compatible across multiple substrate types, this filler streamlines inventory management for shops working on diverse vehicle materials. The yellow color provides clear contrast for even application and sanding guidance.

This product contains 332 g/l VOC content and requires proper ventilation during application. Always follow manufacturer guidelines for mixing ratios, flash times, and appropriate personal protective equipment to ensure optimal results and workplace safety.
