General Finishes High Performance Top Coat — Award-Winning Wood Finish

General Finishes High Performance Top Coat earned Fine Woodworking magazine's Best Overall Choice Award as the hardest and most durable consumer polyurethane topcoat tested. It delivers excellent adhesion to most wood surfaces, dries clear with minimal color shift — making it an ideal choice for light-colored woods and projects where preserving the natural look of the wood is a priority.

The General Finishes High Performance Top Coat is water-based, which means faster dry times, lower odor, and easy cleanup — without sacrificing the hard, abrasion-resistant film that woodworkers expect from a quality topcoat. It is well-suited to furniture, cabinetry, floors, and any project that will see regular use and handling.
