Evercoat Tiger Hair Fiberglass Reinforced Body Filler — 32 fl oz Waterproof Long-Strand, High-Strength Repair

Evercoat Tiger Hair is a long-strand, fiberglass-reinforced polyester filler engineered for heavy-duty repairs and bulk filling where high strength and waterproof performance are required.

This 32 fl oz container of Evercoat Tiger Hair delivers a reinforced body filler that avoids the need for separate fiberglass matting. Formulated with long fibers and a polyester base, it’s designed for demanding automotive and industrial repairs—bridging gaps, filling rusted panels, and restoring SMC, fiberglass, rigid plastics, steel, galvanized steel and aluminum. The product ships with a blue cream hardener and is part of Evercoat’s long-standing range of advanced repair materials.

How does Tiger Hair handle large or rusted areas?

Tiger Hair’s long fiberglass strands give structural integrity inside deep fills, so large voids and corroded areas stay supported as the filler cures. It resists sagging and provides a firm base that can be trimmed, sanded, and shaped for subsequent bodywork.

• Use for bulk-filling holes, replacing corroded metal sections, and building up low panels.
• Works without separate fiberglass cloth or matting for time savings.
• Blue cream hardener included for consistent cure and work time.
• Suitable for vertical and overhead applications when applied in controlled layers.

Can I use this filler on different automotive substrates?

Yes. The polyester formulation bonds to a variety of common repair surfaces after proper preparation. It’s compatible with SMC and fiberglass repairs as well as steel, galvanized panels, aluminum, and many rigid plastics when using recommended adhesion steps.

• Prepare by cleaning, abrading, and using appropriate primers or adhesion promoters when necessary.
• Adheres well to metal and composite substrates used in automotive bodywork.
• Avoid applying directly over active rust; remove loose corrosion first for best results.

What are the workability and finishing characteristics?

Evercoat Tiger Hair provides a resilient, sandable surface after cure that accepts subsequent primers and coatings. Its long-fiber structure minimizes shrinkage and improves resistance to cracking under mechanical stress.

• Trim and shape with standard body tools; sand with coarse to fine grits to final profile.
• Minimal shrinkage helps preserve built-up profiles for easier finishing.
• Compatible with high-build primers and paint systems used in auto body shops.

How should I mix and apply the filler safely?

Mix the filler with the supplied blue cream hardener at the recommended ratio and work quickly within the product’s working time. Apply in layers for deep fills and allow each layer to cure before adding more to avoid overheating and ensure optimal strength.

• Follow manufacturer’s mix ratio; excessive hardener shortens working time.
• Work in well-ventilated areas and use PPE: gloves, eye protection, and a respirator when sanding.
• Cure fully before sanding and painting to achieve proper adhesion and finish quality.
