Evercoat Kitty Hair Long Strand Fiberglass Filler — 32 oz | Reinforced Filler for Fiberglass & Sheet Metal

Overview

Evercoat Kitty Hair Long Strand Fiberglass Reinforced Filler is designed to help you rebuild and reinforce damaged fiberglass and torn sheet metal. The formulation uses long chopped fiberglass strands to add strength to standard fillers, delivering a tougher, more durable surface that can be sanded and finished with typical body shop tools. The product is waterproof and rustproof, and it can be applied without fiberglass mat or cloth, making it a convenient option for mixed-material repairs. The blue hardener included supports you in controlling cure time, so you can plan steps around your workflow.

Key benefits

• Strengthens standard fillers with added fiberglass strands, helping bridge small to moderate imperfections.
• Reinforces torn or rusted sheet metal, including areas on boats and vehicles, to extend service life.
• Waterproof and rustproof properties resist moisture and corrosion during subsequent finishes.
• Easy sanding with 80 grit paper to achieve a smooth, paint-ready surface.
• Versatile on steel, aluminum, fiberglass, and other common substrates for mixed-material repairs.

Real-world scenarios

Think of patching a dented boat hull or repairing a rusted door panel. Kitty Hair can be applied quickly to bridge gaps and reinforce weak spots before priming and painting. Its ability to cure with predictable color and texture helps you gauge progress without slowing down the project.

Usage guidelines

• Prepare the surface by cleaning and lightly scuffing to improve adhesion.
• Mix with the blue hardener according to the instructions to achieve the desired cure time.
• Apply in thin coats, allowing each layer to cure before adding the next.
• Sand progressively from rough to fine grits to achieve a uniform finish.
