Evercoat Metal Glaze Ultra Polyester Glazing Putty — 30 fl oz, thin-flow finish coat for steel, aluminum & fiberglass

This 30 fl oz Evercoat Metal Glaze Ultra formula uses EcoResin technology and ZNX-7 adhesion chemistry to provide an exceptionally smooth sanding surface and reliable bond across steel, aluminum, fiberglass and other common panel materials. Its thinner flow makes it easy to blend with other Metalworks products and ideal for final contouring before primer and paint.

How will Metal Glaze Ultra improve my finishing workflow?

Metal Glaze Ultra is formulated for quick feathering and fast, clean sanding so you can move to primer or paint faster with fewer passes. The thinner viscosity spreads evenly, reducing the need for heavy filling layers and simplifying final shaping.

• EcoResin base for consistently fine sanding dust
• Thin flow improves featheredges and reduces visible transitions
• Compatible as a topcoat over conventional body fillers
• Works well for small spot repairs and large panel finishing

Can I use this putty on different substrate types?

Yes — Metal Glaze Ultra bonds to steel, aluminum, and fiberglass when used on properly prepared surfaces. Its ZNX-7 enhanced adhesion increases reliability across common automotive substrates, though standard surface prep remains important.

• Suitable for steel and aluminum panels after cleaning and sanding
• Adheres to fiberglass with appropriate etching/cleaning steps
• Works over cured body filler as a finishing layer
• Avoid application on oily or contaminated surfaces for best results

What are the practical mixing and application tips?

The product’s thinner consistency is intended for spreadability and intermixing with other Metalworks items to improve flowout. Use the recommended polyester hardener at manufacturer-recommended ratios and apply in thin layers, sanding between applications as required.

• Use the correct peroxide hardener and mix thoroughly for consistent cure
• Apply in thin coats to avoid sagging and to speed sanding readiness
• Sand progressively with fine abrasives for best finish before primer
• Intermix with compatible Metalworks products to alter flow and body
