Top Coat White Gallon

The POR-15 Top Coat White Gallon is a professional-grade urethane topcoat designed to protect and seal surfaces exposed to harsh environmental conditions. This one-gallon can delivers a durable, hard-wearing finish ideal for automotive restoration, industrial equipment, metal structures, and corrosion-prone applications where superior paint adhesion and longevity are essential. Whether refinishing a classic car, protecting machinery, or sealing metal surfaces in demanding environments, this white topcoat provides the protective barrier serious enthusiasts and professionals demand.

Formulated as a premium urethane coating, POR-15's Top Coat White creates a high-gloss, chemically resistant finish that bonds permanently to properly prepared surfaces. Urethane topcoats cure harder and faster than standard enamels, offering superior resistance to gasoline, oil, brake fluid, and extreme temperatures—critical advantages for engine bays, fuel tanks, and underbody protection. The thick, self-leveling formula minimizes brush marks and ensures even coverage, while its advanced resin structure resists yellowing, fading, and UV degradation over extended periods of exposure.

This gallon-size container suits both small restoration projects and professional shop applications. POR-15 urethane topcoats perform best when applied over properly primed metal surfaces and are compatible with most standard automotive primers and basecoats. For optimal results, ensure surfaces are clean, dry, and lightly sanded before application, and allow adequate cure time per manufacturer specifications before exposing the finished surface to fluids or weather. Professional detailers, restoration shops, and serious DIY builders rely on POR-15 formulations for finishes that endure decades of use.
