I agree, plastic is cheap, and apropos for the very few times I might use a VBL. Probably more susceptible to puncture than fabric, though. Another poster (Rich Mitchell <mitchelr_at_ucs.orst.edu>) mentioned that PU coatings will eventually emulsify if kept wet and warm (and, in contact with the oils, acids, etc., from body perspiration?). This jives with my experience with various items of PU-coated raingear, over the years. I don't know the exact mode of degradation, but the PU coatings definitely fall apart within a couple years of frequent use. Anybody (beyond Rich) noticed this with VBL's? Rich also claimed to have good luck with silicone-coated fabric as a VBL, and referenced some Stephenson-manufactured gear, I think. I am unfamiliar with the properties of silicone-coated fabrics, and would not know where to get them. Anybody know? -- Dave Kruger Astoria, OR *************************************************************************** PaddleWise Paddling Mailing List Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.gasp-seakayak.net/paddlewise/ ***************************************************************************Received on Tue Oct 20 1998 - 15:02:26 PDT
