Noah, I've seen a C34 where they just painted a non-skid product over the existing non-skid, it honestly didn't look good (to me) and I just remember thinking how darn easy it was to sand the non-skid down flat to apply the new gelcoat. Honestly, sanding it down was the easy part!!!
Jim, I don't know about Dave's boat but on our C-34 the non-skid is worn completely thru in a few areas, it just looks like they sprayed the mold a bit thin in these areas. I've seen this on other boats including other C34's, C27's, etc. The gelcoat is just gone.
I didn't mention it the other day but has anyone had experience with Totalboat's "TotalTread Non-Skid Marine Deck Paint"? I have had very good experience with all their other products and find them to be very good quality. A friend of mine painted his deck on his Laser with it and it looked pretty good. The results on their website look outstanding as an alternative the the really pricey products so I'm curious regarding others real world experience?
