Welcome HIFLUTIN.....Thats a tuff one, if you re-gel or repaint the floor kiss the diamond non-skid goodbye. You will have to re-apply a new non-skid coat. The most typical, is a uniform non-skid across the whole floor and or deck cap. Depending on your budget and or skill set you can have a patterned non-skid deck. When I did my floor, we used half inch tape running from bow to stern with a two inche gap between each strip of tape. My deck has smooth half inch stripes running from bow to stern like the old Sea Crafts, looks real sharp.I'm sure others will chim in with ideas and tips. Good luck!
Marc, the stuff JD used was called Durabak. It turned out real nice. Supposed to be very similar to Kiwigrip.
