I used it on my deck and nonskid
and it was fine. It's certainly easier to clean (which matters on a 40' boat.) I wouldn't say that it actually increased traction though. You do have to be carefull about any oils that accumulate (tan lotions from the babes laying on deck, etc.) because combined with any moisture it sits on top of the Poli-Glow finish and can be slippery. Keep the deck clean and it's fine however. I'd do it again. I've been using this stuff for 8 years. Great product.
