Was the non skid painted on after the decks were done and is it just paint or real gel coat material... the reason I ask is if a drop of oil hits it, it seems to suck it up and hold it. I have even though of using something like armor-all to get it even as far as the darker spots, but then again its non skid and it would defeat the purpose and probably kill me

So the real question is has anyone noticed this and found a way to clean it ?
Thanks
Matt
