U-Pol Fibral Lite Fiberglass Filler, 3 Liter

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.

• 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

Substrates: Fiberglass, steel, plastics
