Not familiar with Evercoat
But I did apply the West Marine non skid on my Hunter last year. I had made temporary repairs to a wet core that needed to be covered. The non skid applied very easily and consistently. I used a brush and once dried, I could see no evidence of brush strokes. It seems to be holding very well and it made a huge improvement to the appearance of the boat. It also was "grippier" than the original molded non skid. It is not uncomfortable to sit on and seems to take to cleaning well. I used about two thirds of a gallon for the whole 27' boat (most of the deck, cabin top, cockpit are nonskid) for two coats.I made a permanent repair to the core over the winter and when I went to repaint the non skid areas, I found that the paint I had left, most of the non skid material in the paint can had clumped together and floated on top of the paint. I tried using a mixing attachment on a drill to try and break it up but it stayed in large chunks. Maybe I can get some of the material and mix it in with the good remaining paint...Hope this helps,Manny
