The Quantum High Solids Repairable Marine Finish System is Now Available in an Easy-To-Use Aerosol Spray

Before the introduction of Quantum99, 2 part topside paints were for professional use only. Complicated reducers, activators, and primers meant that 2 part polyurethane systems were mostly used by builders, yards, and professional paints.

Quantum99 has raised the bar again for topside paint systems, because now it's available in a two-component aerosol spray that's easy to use for touch-ups or for coating smaller areas.

Quantum99 has garnered rave reviews and proven results for superior gloss, gloss retention, and durability. Easy to use. Easy to repair. Its high-solids, eco-friendly formula ensures fewer coats and VOC compliance.

Caution: Application of these product systems requires recommended temperature/humidity conditions and film thickness ranges. The material, hangar, and substrate temperature should be no lower than 45°F before, during, and after application. Do not apply paint materials to surfaces less than 5°F above the dew point, or to surfaces warmer than 125°F. Substrate temperature should be minimum 45°F to maximum 125°F.

Notes: Air dry and overcoat times are dependent on shop conditions. To accelerate dry times, use Quantum99 Urethane Accelerator (sold separately). If recoating after 24 hours, scuff-sand with 320-800 grit sandpaper.

Application issues


Used on a jet ski. On long spay patterns, had spitting from the can, which caused runs. Nice finish otherwise. Would use again but would look for more application guidance
