warbird I mainly am used to using West Systems for all my epoxy resin needs. Usually to strengthen the resin I add some of the structural fillers that they have. Is this along the lines of what you are talking about? I have had quite a successful amount of repairs done with this mixture and have been happy so far. I am just looking to put something on there that will last for a while. Of course I know that it will last longest by not dragging it on the sand <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />
