Review: Good product - Refinished the outside door and applied three layers. The door is facing the sun, in direct sunlight. For 8 months, it has held good. By the way, the application was easy, and it dries fairly fast.
Review: Easier to get a perfect finish than other spray urethanes - I have used tons of this stuff over the years for restorations. In my opinion, the Minwax Helmsman clear gloss spray spar urethane is the best finish freely available in the southeast United States. I have used many different common finishes over twenty-plus years. The difference that I like so much is that the spray is very thin. Getting a perfect, smooth, even surface is easier with the nozzle and formulation with this product. It is not perfect. The coverage is poor, the color is tinted, and the dry-time is long. Also, it can't be used on top of water-based paints. Every finish has its use. I just come back to this one the most.
