U-POL Dolphin Glaze self-leveling polyester finishing filler 440ml — bonds to metal, fast solvent resistance

U-POL Dolphin Glaze is a self-leveling polyester finishing filler in a 440ml spray that produces an exceptionally smooth, tack-free surface and bonds directly to metal. This polyester-based finishing glaze is formulated to level out minor surface irregularities and create a smooth foundation for subsequent coatings. Designed for use on automotive and metal repair projects, it combines strong adhesion with quick solvent resistance and straightforward sanding. The aerosol 440ml format makes it convenient for spot repairs, panel finishing and small-scale workshops where ease of application and fast turnaround matter.

How quickly does Dolphin Glaze become solvent-resistant and ready for handling?

After application, the glaze develops resistance to solvents within roughly 15–20 minutes, allowing for faster progression to the next repair stages. Full cure and optimal sanding properties depend on film thickness and ambient conditions, so allow additional time when layers are heavier or temperatures are low.

• Solvent resistance: approximately 15–20 minutes under normal conditions
• Thicker coats increase cure times—apply thin, even layers
• Warm, dry environments speed drying; cold or humid conditions slow it

What surface preparation and application technique work best?

For the best bond, clean the substrate of grease, rust and loose paint before spraying — the product is suitable for direct-to-metal use when correct preparation is observed. Shake the can thoroughly, apply light, cross-coats and allow each pass to level; aim for an even film to take advantage of the self-leveling properties.

• Degrease and abrade surfaces to remove contaminants
• Shake can well and spray several thin coats rather than one heavy coat
• Maintain recommended spray distance for uniform coverage

How easy is it to sand and finish after application?

The glaze sands down smoothly, making feathering and surface shaping straightforward compared with tougher fillers. Use progressively finer abrasives to refine the finish before primer or topcoat, and avoid aggressive sanding immediately after a fresh, tacky application.

• Sands easily to a smooth profile for primer or paint
• Start with medium grit and finish with fine grit to remove scratches
• Allow proper cure before dry sanding to prevent gumming

What safety and storage practices should I follow?

Use in a well-ventilated area and follow standard aerosol safety: wear respiratory protection, gloves and eye protection when spraying. Store the can in a cool, dry place away from heat sources and discard according to local hazardous-waste guidelines when empty or expired.

• Wear appropriate PPE: respirator, gloves and goggles
• Store upright in a cool, ventilated area away from direct heat
• Dispose of empty cans following local regulations

Who is this for This 440ml U-POL Dolphin Glaze is aimed at bodyshops, DIY car restorers and metalworkers who need a fast, easy-to-apply finishing product that bonds well to metal and sands smoothly. It's especially useful for spot repairs, panel finishing and situations where quick solvent resistance and a level surface are required before primer and topcoat application.

FAQ

Q: Can Dolphin Glaze be sprayed directly onto bare metal?

A: Yes—when the metal is clean and abraded; proper surface prep is required for good adhesion.

Q: How long should I wait before sanding the glaze?

A: Allow solvent resistance in 15–20 minutes, but wait longer for full cure depending on coat thickness before sanding.
