Evercoat Z-Grip Lightweight Body Filler 128 fl oz (1 Gal) — Adhesion for Aluminum & Fiberglass, Easy-Sanding

Evercoat Z-Grip Lightweight Body Filler (128 fl oz) is a professional-grade, easy-sanding putty formulated for strong adhesion to aluminum, fiberglass, galvanized steel and other automotive substrates.

Designed for collision repair shops, restorers and experienced DIYers, this large-capacity Z-Grip formula balances lightweight handling with robust fill and adhesion. The formulation includes Hattonite to reduce sanding heat and friction, a clog-resistant mix to stretch sandpaper life, and chemistry optimized for hard-to-bond metals like aluminum and galvanized surfaces.

How does this filler simplify sanding and finishing?

The Z-Grip formula sands smoothly with less effort thanks to friction-reducing additives. That means faster feathering, fewer clogged grits, and a cleaner surface ready for primer or topcoat.

• Contains Hattonite to lower sanding heat and friction
• Sands easily with 80-grit sandpaper for rapid stock removal
• Clog-free characteristics extend sandpaper life and reduce downtime

Will this product stick to aluminum, galvanized steel, and fiberglass?

Yes — Evercoat engineered Z-Grip for superior adhesion to metals and composites commonly encountered in vehicle repair. The binder system promotes a secure bond to galvanized and aluminum panels where many fillers struggle.

• Proven adhesion to aluminum and galvanized steel surfaces
• Formulated for use on fiberglass and conventional steel
• Reduces lifting and delamination when mixed and applied per instructions

What makes this 128 fl oz size practical for shops and restorations?

The 1-gallon (128 fl oz) container gives ample material for medium to large repairs and repetitive jobs without frequent reordering. It’s a cost-effective option for busy shops, restoring classic vehicles, or prepping multiple panels at once.

• Large-volume packaging reduces unit cost for high-use environments
• Better for batching several repairs or panel runs in one session
• Compatible with standard Evercoat hardeners and application tools

How should I apply and finish Evercoat Z-Grip for best results?

Apply to clean, dry, and properly abraded surfaces using a metal or plastic spreader. Work in thin layers to avoid excessive exotherm, let each layer cure, then shape with 80–180 grit sanding before primer.

• Prepare surface: remove rust, oils, and contaminants; roughen with appropriate grit
• Mix with recommended hardener in correct ratio; apply thin, buildable coats
• Sand starting with 80 grit for bulk shaping, finish with finer grits before priming

Who is this for? Evercoat Z-Grip Lightweight Body Filler (128 fl oz) is aimed at professional autobody technicians, restoration hobbyists, and fabrication shops that require a large-quantity filler capable of bonding to aluminum, galvanized steel, fiberglass and standard steels. If you regularly perform multi-panel repairs or prefer buying in bulk to reduce material changes, this size and formula deliver strong adhesion, easier sanding, and reliable filling performance. Follow Evercoat application guidelines and safety instructions for best results.
