The Shurhold Dual Action Polisher came as advertised. Packaged well. Several tracking notifications which was very nice. Our "new" old boat is a 2003 Nordic Tug 42. She has about an acre of non-skid surface which I was working through with a hand brush when I saw the Shurhold video. Purchased a stiff brush, and a soft brush, for the polisher and applied buff magic compound and Pro-Polish wax as instructed. So far I have waxed just the cockpit and the swim step but the areas I have done look awesome and I am very satisfied with both the effort required and the results. Note that the stupid black specs in your non-skid will not buff out (even with the stiff brush)They will not come off with Acetone, or brake clean, or be affected by Goof Off, or pretty much any caustic product you might try. They are black mold (no really) and require bleach. Clorox in a spray bottle will work. They usually need to soak, and a stiff hand brush works best. Once your deck is clean of mold and major stains, the Shurhold Buff Magic Compound, and Pro Polish Wax, apply a great shine, and protective finish which looks almost like new and is not slick to walk on. Great products.
