Universal 2K Primer/Sealer Activator QT

Streamline your auto body shop inventory and achieve flawless foundation coats with the Universal 2K Primer/Sealer Activator. Designed for maximum compatibility, this professional-grade hardener works perfectly with a broad spectrum of 2K urethane undercoats, eliminating the need to stock dozens of brand-specific activators.

Whether you are mixing a high-build primer surfacer to block out body filler or reducing it to a wet-on-wet sealer for uniform topcoat application, this activator delivers consistent, reliable cross-linking. It promotes excellent flow out of the spray gun, reducing texture and minimizing sanding time. Once cured, it creates a tough, solvent-resistant barrier that prevents shrinking, sand-scratch swelling, and topcoat die-back, ensuring your basecoat and clearcoat retain their maximum brilliance.

Ideal for everyday collision repair, custom restorations, and high-production shops, this 1-quart universal catalyst keeps your paint prep moving efficiently.
