Review: Definitely an improvement - Repainted my pretty slippery topside paint. Satisfied with results and have gotten compliments. Generally followed manufacturer’s instructions. Biggest pain was taping. I was fortunate to have a good weather window. But still did it in stages, mostly to keep my dog from walking in it when it wasn’t dry. Primer dries quickly. First coat takes awhile to dry. Covers fairly well. Second coat dries much faster but still tried to avoid walking on it for a bit. My advise is to keep stirring/mixing it, in the can and even in the tray. I started off using a 6” foam roller but found that it didn’t spread the grit very well. I found that l had much better results with that when l switched to a 1/4” nap “regular” roller. Just my opinion. My deck already had a tannish color so l chose to go with the sand color. I think it looks nice but my only real concern with it will be keeping it clean. In that regard for the places where we (dirty dog feet) board amidships l have decided to put down some foam decking. desertcart carries different choices but l elected to use the Sailrite offering. Haven’t put it down yet but it’s on the list. I’m also putting some in the cockpit in front of the companionway. All in all, so far l am satisfied.
Review: Great Base Layer - I put this down first, before TotalBoat Wet Edge. Went on easily. Cured quickly. Helped build a solid base.
