Ok, sorry for mentioning the "W" word but I'm looking for some info on a winter cover/tarp. A "winter neighbor" told me he found his from Cruising World magazine that had an article once about different types of covers verses covers, shrink wrap, canvas, poly, etc. The one I hhe had came highly recomended and was an off white looking heavy poly,? or at least it resembled poly. The guy had some rolls of white tape that he used with it and said it came from an outfit in Texas. His boat was covered for four years and thru the Ohio winters and summers without any problems. Lets light in, strong and cost was inbetween canvas and the cheaper poly types. What is this mystery material and where can I find it???? thanks, howie~
