Thanks for the appreciation, nice to know someones listening. Need clarification for your present problem. Most people when they say top sides mean the hull above the waterline but I'm assuming you mean your deck, since you probably dont have non-skid on your hull. What is the problem with said non-skid? Flaking paint, or a repair? Do you just want to paint over it to change the color? What is the deck made of? Is your anti-slip or non-skid a molded in pattern or a grit material? What kind of finish do you want to end up with? Are you coating over gelcoat or paint? Lots of questions I know. Just trying to help out.
Didn't I give you some pointers on cleaning water out of a diesel tank? How did that go? Hope it helped you.
On another subject, whatcha ridin'? Mines a V-Strom DL1000. Boats and bikes, yay!
