The Premium HS Fast Clearcoat Set 2:1 (1.5L) – 1st KLASS is a high-solid, low-VOC acrylic clearcoat system designed for rapid automotive refinishing.
Its high resin content ensures excellent leveling, deep gloss, and a visually flawless finish.
This clearcoat stands out for its extremely short drying times — even at 20°C it becomes dust-free within minutes, and reaches touch-dry state in 90 minutes. When force-dried at 60°C, full curing occurs in only 15 minutes.

It can be applied over solvent-based or water-based basecoats, as well as properly prepared existing coatings.
