Interlux Toplac Plus is a premium one-part polyurethane topside paint formulated for above-the-waterline surfaces on fiberglass, wood, and primed metal. Matterhorn White (YLK199) is a clean, bright white finish well suited to hull topsides, cabin sides, and deck structures where a durable, high-gloss appearance is the goal.
Toplac Plus delivers excellent UV resistance and color retention, maintaining its gloss over multiple seasons with proper preparation and application. The one-part formula is easier to apply than two-part systems and can be brushed, rolled, or sprayed. This listing is for a one-quart (946 mL) can.
Parts Desk Insights
Best Use Case: Toplac Plus Matterhorn White is the right choice for refreshing or repainting hull topsides, cabin structures, or cockpit surfaces on fiberglass or wood boats where a factory-quality white gloss finish is needed without the complexity of a two-part system. It performs well as a seasonal refresh coat over a sound existing Toplac or compatible polyurethane finish, and is a strong choice for trailer boats that see frequent sun exposure.
Application Notes: Surface preparation is critical — clean, sand, and prime bare or weathered surfaces before applying. For best flow and leveling when brushing or rolling, use with Interlux Brushing Liquid 333 or 2333N. A foam roller followed by a light tip-off with a quality brush produces a near-spray finish on flat panels.
