U-POL Maximum Fibral Lite® Lightweight Sandable Fiberglass Filler

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

• Spreads like a short strand yet bridges holes like a long strand
• Non-sagging even on vertical surfaces - spreads, adheres and finishes like a polyester filler
• Forms a hard, durable surface that is still smooth and very easy to sand
• Waterproof
• Can be finished with putty or glaze or directly primed
