I was interested in reading Bill Martins note concerning canvas and its maintenance. I have a soft top which is now 7 years old and near the end of its life. It was recently stitched in an effort to get another year or so out of this blue vinyl fabric. We now have several hundred new holes where the stitching allows free passage of water. The vendor knew of nothing that would stop leaks other than beeswax! What is marine goop and where is it available? Thanks John Marquardt, M/V Water Marq, Eastbay 38
