There are some flexible molds available to recreate nonskid patterns. I have never used one, but they exist. Used properly, you cannot tell.

One source for this product is: Gibco Flex-Mold. (gibco@swbell.net) Phone 817-236-5021. No website, sorry.

I have had good luck with the Interlux polymeric nonskid particles mixed into the paint. They seem to hold up well, and it is a very easy system to use successfully. I used it first on my Ensign, and that deck is still going strong 5 years later. I used the same thing on my Triton and am pleased with the results--both functional and cosmetic. It requires removing the existing pattern, though. (as far as I'm concerned anyway)
