Product Description

Professional-grade 2K catalyst hardener engineered specifically for automotive urethane primers. This high-performance clear catalyst transforms your Eastwood gray, buff, or black urethane primers into an ultra-durable foundation ready for topcoat application. The 4:1 mixing ratio ensures perfect consistency every time, while the crystal-clear formulation won’t alter your primer’s color or thickness. Once cured, this catalyst creates an incredibly tough, sandable surface that bonds tenaciously to metal, fiberglass, and properly prepared substrates. Designed for professional collision repair, restoration projects, and custom automotive painting, this primer catalyst delivers the factory-quality finish demanding builders and enthusiasts expect. The easy-to-spray formula flows smoothly and levels beautifully, reducing runs and sags. After full cure, sands effortlessly to perfection, giving you the ideal surface for basecoat clearcoat or single-stage paint systems. Trusted by professional shops and serious hobbyists alike, Eastwood combines 80+ years of automotive expertise with innovative product design. For optimal results, apply in a well-ventilated area using proper respiratory, eye, and skin protection. Pair with Eastwood Gray Urethane Primer (50240ZP) for the ultimate primer system.
