Just applying the last few coats of varnish on my Great Auk and I was reading through the label on the can and noticed something I hadn't seen before..."DO NOT USE BELOW THE WATERLINE"...What?????? I am using Z-SPAR 2015 flagship varnish which was recomended to me as "great" for this application. Can anyone provide advice to me as to how to proceed? I am trying to finish up for a trip to the Everglades in January. Thanks. Also, still looking for advice on where to find a skirt to exactly fit my Great Auk cockpit. Are they readily available or do I need to have one made? Thanks
