Second all the positive reports here. We got our decks a bit too stippled (hot day, working too-large sections), but it sure is grippy! For the cockpit seats and coaming tops, we spread a thinner layer and rolled it with a cheap foam roller cover; result is a lightly suede texture that is easy on clothes and skin but MUCH safer than the molded non-skid was. It does show dirt. Good product, good customer service from the West Coast distributor. When the time comes, our 30'er will be getting KG. Not even considering anything else.
To prevent unused KG from hardening in the can, decant into smaller jars & top with Bloxygen or propane. It's super-easy to touch up any gouges.
