This UV-Cure Sanding Resin (Hot-Coat) is pre-blended with a surfacing agent, allowing it to cure completely tack-free. Unlike chemical-kick resins, the UV formula gives you infinite time to brush out your hot-coat to perfection. Once you're ready, simply expose it to sunlight for an instant, hard cure that is ready to sand in minutes.

Product Highlights:

Instant Sanding: Reaches a full, hard cure in minutes when exposed to UV light.

Infinite Work Time: Brush and level your resin without the pressure of a ticking clock.

Tack-Free Finish: Formulated with wax to ensure a smooth surface that won't clog sandpaper.

Universal Repair Choice: The most popular choice for professional-grade, fast ding repairs.

Shelf Life: Guaranteed 1-year minimum shelf life.

Pro Tip: For the flattest finish, brush your hot-coat in a cool, shaded area to let it self-level. Once it looks like glass, move it into the sun to "lock" that finish in place instantly.
