Evercoat Everocat Kitty Hair Fiberglass-Reinforced Filler 32 fl oz — Long-Strand Strength for Fiberglass & Sheet Metal

Evercoat Everocat Kitty Hair is a long-strand, fiberglass-reinforced polyester filler designed to rebuild shattered fiberglass and reinforce torn or rusted sheet metal without the need for additional mat or cloth.

Built for body shops, boatyards, and DIY restorers, this 32 fl oz tub of Everocat Kitty Hair combines chopped long-strand fiberglass with a waterproof polyester filler formula to deliver greater tensile strength than standard putties. Supplied with a blue hardener, the compound bonds to steel, aluminum, and fiberglass and sands readily for fast feathering and finishing. Evercoat’s decades of product development back the formulation, offering a professional-grade solution for structural and cosmetic repairs.

How does this filler add strength to fiberglass and sheet metal repairs?

Kitty Hair contains chopped long strands of fiberglass embedded in a polyester matrix, which distributes stress across the repair rather than concentrating it at one point. The long fibers act like tiny reinforcements within the cured putty, delivering improved flex and resistance to cracking compared with conventional, non-reinforced fillers.

• Long-strand chopped fiberglass increases tensile strength and impact resistance.
• Forms a waterproof, rust-resistant bond over fiberglass or corroded metal.
• Works without separate fiberglass matting for quicker, simpler repairs.

Can I use Everocat Kitty Hair on different substrates like aluminum, steel, and gelcoat?

Yes — the product is formulated to adhere to a range of automotive and marine surfaces when properly prepared. Scuff, degrease, and remove loose corrosion or delamination before applying; on highly oxidized or contaminated surfaces additional preparatory steps may be necessary.

• Suitable for steel, aluminum, original fiberglass, and gelcoat substrates.
• Requires clean, dry, and abraded surfaces for optimal adhesion.
• Recommended for patching rust-through, tears, and shattered fiberglass areas.

What is the application and finishing process for achieving a smooth repair?

Mix the filler thoroughly with the supplied blue hardener in small batches and apply with a spreader to fill voids or build up profile. After curing, Kitty Hair sands easily using coarse to medium grits for shaping, then finer grits for feathering prior to primer and paint.

• Mix ratio: follow hardener manufacturer guidance — typically low-volume additions for controlled working time.
• Apply in layers for deep repairs; use 80-grit for shaping, finer grits for finish sanding.
• Overcoat with compatible epoxy or primer before topcoat for best longevity.

What practical benefits do shops and DIYers gain from this filler?

Everocat Kitty Hair shortens repair time by eliminating the need to lay separate fiberglass cloth for many applications, while providing a durable, waterproof patch. Its long-strand reinforcement reduces the likelihood of future cracking in stressed areas, making it a go-to product where strength and speed matter.

• Reduces steps compared with cloth-and-resin repairs in many scenarios.
• Waterproof and rustproof properties increase long-term durability.
• Easy sanding helps accelerate repair-to-paint cycles.

If you repair boat hulls, patch rusted panels, or rebuild shattered fiberglass components and want a strong, sandable, waterproof solution, this 32 fl oz tub delivers the reinforced performance required for reliable structural and cosmetic results.
