I've been researching non-skids for the Wanderer and trying to make my mind up between durabak and kiwigrip. I have to assume they are at least pretty simular products. I know that durabak is good. I personally applied it to a DNR research vessel last spring. The crew seems to love concrete blocks as well as iron for bouy anchors so I have to admit that I was surprised when it came back in fall how good of shape the nonskid was in. It was the gray but looked like new. I also have to admit that I was still curious so I myself dragged/(somewhat lightly) dropped a couple of their blocks on the surface with seriously no effect at all. Even some of the 2 part epoxy smooth paint was chipping off. But the durabak was solid. I also have a friend who used the durabak and just took his boat to Florida this year. He reports no problems with his nonskid except for bike tires (he stores them on deck) wanting to stick to it on very hot days. Some of the photos from previous threads here have been just been leaning me towards kiwigrip. Especially the edges of the durabak peeling. After all the work of sanding all the gellcoat nonskid off my deck that would piss me off. I can't help wondering if that must just have been some "not perfectly prepped" areas though. Maybe not roughed up or entirely wax/oil free?
