Evercoat Polyester Glazing Putty for Galvanized Steel & Aluminum — 20 oz, fast-curing ZNX-7 formula

Evercoat Polyester Glazing Putty is a smooth, fast-curing paste putty formulated to fill grind marks, pinholes, and shallow body damage on galvanized steel, aluminum, fiberglass, and OEM finishes.

This 20 oz kit pairs Evercoat's ZNX-7 adhesive formula with a blue cream hardener to deliver a tack-free surface that sands quickly and bonds reliably to challenging substrates. Designed for professional and DIY auto body repair, the putty handles low spots and defects up to 1/8-inch deep and integrates into standard refinishing workflows. Evercoat has produced industry-grade fillers and primers since 1953 and engineered this glazing putty to work across metal, composite, and coated surfaces without the lifting or delamination common with lower-grade products.

How well does this putty adhere to galvanized and coated panels?

Evercoat's ZNX-7 chemistry provides improved adhesion to galvanized steel, e-coated panels, bare steel, aluminum, and cured OEM finishes. The result is reduced edge lift and a more dependable bond, even on harder-to-stick substrates. Use the recommended surface prep for best results.

• Bonds to galvanized steel, e-coat, aluminum, SMC, and OEM paint
• Formulated to resist lifting on coated or zinc-plated surfaces
• Works over properly prepared bare metal and composites

How easy is the product to apply and sand?

The putty has a smooth paste consistency that spreads easily with a spreader and requires only a thin application for most imperfections. It cures quickly when mixed with the included blue cream hardener and sands clean with 180-grit sandpaper, allowing fast progression to primer and paint steps.

• Smooth paste texture for uniform feathering and filling
• Cures fast with supplied hardener — ready to sand with 180 grit
• Sands to a stable surface for primer application

What types of repairs can I use it for?

This glazing putty is intended for small cosmetic and repair tasks, such as filling grind marks, pinholes, and minor low spots. It can also be used to rectify light body damage up to 1/8-inch deep, but is not intended as a replacement for large panel rebuilds or structural repairs.

• Fills pinholes, minor pits, and small low areas
• Repairs shallow dents and cosmetic flaws up to 1/8-inch depth
• Ideal finishing layer before primer on auto body panels

What preparation and safety steps are recommended?

Proper surface prep ensures adhesion: remove loose paint, rust, and contaminants, then abrade with appropriate grit. Use the correct ratio of putty to hardener; avoid overly thick applications. Follow standard ventilation and PPE practices when sanding or applying polyester products.

• Clean, degrease, and abrade surfaces before application
• Mix with the supplied blue cream hardener at recommended ratios
• Use respirator and eye protection; ventilate when sanding or curing
