How is Clear Shield™ Protective Finish different from Minwax® Fast-Drying Polyurethane?
Minwax® Clear Shield™ is an oil-based spar urethane that dries to a tough, abrasion-resistant surface. Unlike Minwax® Fast-Drying Polyurethane, Minwax® Clear Shield™ is a flexible finish that expands and contracts with changes in temperature and humidity. It contains ultraviolet absorbers to help protect wood from the graying and fading effects of the sun.
