Below is what I posted a while back in another thread:
Because I'm rebuilding the entire deck I won't be trying to reproduce the factory non-skid. I had great success with the process I used on the last boat and intend to use it again.
Quick overview of the steps:
1) Using a quality paint scrapper, scrap off the non-skid.
2) Sanded down the "smooth surfaces" with a board sander at 80 grit.
3) Sand down the "non-skid" surface with 80 grit.
4) Spray Awlgrip 545 primer to appropriate coverage thinkness (after deck has been properly cleaned).
5) Sand down the primed surface at 220 grit.
6) Spray Awlgrip on "smooth surfaces".
7) Tape off/cover "smooth surfaces".
8) Mix awlgrip (as directed) with flattening agent, then mix in Colloidal Silica until the paint is as thick as peanut butter.
9) Spread the mixture onto the non-skid area and roll it with a medium nap roller.
10) Let dry and remove the tape.
That's it and (in my opinion) you will get a beautiful, long lasting result. It will look like the non-skid on C&Cs as well the non-skid used on J120s.
