I've got a couple sprayskirts of the neoprene deck/coated nylon tunnel variety which have lost waterproofness on the tunnel. The loss of coating seems to be worst where they were flexed (or abraded) the most. So, I bought a can of Recoat (a Kenyon product, I think), which is a water-based emulsion of the polyurethane stuff which composed the original waterproof coating. It is recommended for renewing the waterproof coating on nylon. Per the instructions, I washed the nylon in warm soapy water, rinsed thoroughly, allowed it to dry, and then brushed the Recoat on. After the requisite several days, used the sprayskirts on an overnight tour. Disaster! The re-coating is coming off in strips, particularly where it contacted itself. What gives? Does anybody have a technique/material which will lay down a durable waterproof coating on nylon? I am loath to abandon these sprayskirts. Other than the loss of waterproofness on the tunnel, they are in very good shape. P.S. These are from Snapdragon, a reputable and popular brand out here. -- Dave Kruger Astoria, OR *************************************************************************** PaddleWise Paddling Mailing List Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.paddlewise.net/ ***************************************************************************

Cut off the nylon and make a tube with the neoprene--cut the seam out of the old nylon tunnel and use it for a pattern. Use Aquaseal and you shouldn't have to sew anything. >I am loath to abandon these sprayskirts. Other than the loss of waterproofness on the tunnel, they are in very good shape. Or, you could send them to me, with the knowledge that they'll be used, loved, and not at all abandoned! :) Shawn 0 ____©/______ ~~^~^~^~^~^~^~^~^\ ,/ /~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^ Baker Brothers 0 Brews & Boats http://www.missoulaconcrete/shawn/ Shawn W.

Dave: I had the same problem with my Snapdragon sprayskirt. It was just under a year old. I sent it back and they replaced it with a new one. Have yours exceeded the 1-yr warrenty? Have you asked Snapdraggon if they can repair it?

Dave, It is possible that you didn't allow sufficient time for the coating to cure totally. When I covered the bottom of folding kayak with hypalon paint, it took months to cure properly. In the meantime, I would recommend you routinely put baby powder on the newly coated services. This will prevent different portions of the skirt from adhering to each other. - Scott Ives *************************************************************************** PaddleWise Paddling Mailing List Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.paddlewise.net/ ***************************************************************************
Hi Dave, I hate to be the bearer of un-a-peeling news, but the formula for Recoat was changed a few years back (I think it was to make it meet newer safety/environmental standards). The new stuff is so ineffective, my employer (an outdoor retailer) decided we were actually not doing any service to our customers who were hoping to restore their rainwear, tent flys, etc., so we no longer carry it. If you find a product that works please let me know - we'd love to help our customers get more mileage out of delaminated stuff rather than having it go to premature graves in a landfill.

I think I'll send the spare can (unopened) back. This stuff sucks ... errr ... peels. -- Dave Kruger Astoria, OR *************************************************************************** PaddleWise Paddling Mailing List Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.paddlewise.net/ ***************************************************************************
