I'm refinishing my 1987 Catalina 34 Sailboat's Non-Skid decking - all of it. A representative from Catalina recommended that I use Alwgrip and Jamestown has the product. This is the largest 'painting' task I have undertaken but the support from JTD has been excellent. They provided all of the references I needed in order to do the job correctly so that I can get the best result. When I had any doubts, a quick 'chat' online clarified the details. The Primer is two part and then reduced in order to be able to apply with brush and roller. I'm in South Florida - the heat and humidity is an issue, I waited till the crazy summer heat died down and then set to work. So far I have done one side of the Anchor locker lid. I brought that home to practice in the garage. All of the steps described by both the reps from JTD and from the documentation were easy to follow and complete. I would advise that you'll need a lot of mixing cups. I put on two coats of the primer and three coats of the top coat. The result is easily as good as I was expecting, perhaps better.
