Top Coat Silver 15oz Aerosol

The POR-15 Top Coat Silver 15oz Aerosol (Part No. 46018) is a premium urethane-based protective coating designed to seal and finish surfaces that have been treated with POR-15's epoxy primer system. This aerosol format delivers consistent, professional-grade coverage for metal restoration projects where a durable topcoat is essential for long-term corrosion resistance and aesthetic finish.

The 15oz aerosol container provides convenient spray application without the need for compressor equipment or spray gun setup. POR-15's urethane topcoat chemistry chemically bonds to primed surfaces and cures to a hard, impact-resistant finish that resists fuel, oil, salt spray, and UV degradation. The silver metallic finish complements factory-style appearance on automotive, marine, and equipment restoration work. Application is straightforward on vertical and horizontal surfaces, with typical cure allowing light handling within hours and full hardness in days, depending on ambient temperature and humidity conditions.

This product is engineered for restoration professionals and serious hobbyists tackling rust perforation repair, undercarriage protection, frame reinforcement, and engine bay refinishing. It pairs with POR-15 primer systems to create a complete corrosion-barrier solution for vehicles exposed to harsh environments—salt air, road salt, industrial fallout, and moisture. The aerosol format is particularly suited to detail work, tight spaces, and projects where precision and control outweigh volume coating.

For automotive restorers, the POR-15 topcoat system represents a proven approach to permanent rust prevention without stripping or sandblasting. The silver color works well as a base for additional paint or as a finished protective layer on mechanical components where appearance matters but factory paint is not required.
