Tinkering around in my shop, I built a modified Turtledog tripod stand for my hammock. Because I wanted to use my full coverage silnylon rainfly, I designed the ridgepole to do double duty as the ridgeline. I had left it set up in a torrential downpour last night and discovered some water leaked through. The tarp is 3 - 5 yrs old. I was wondering if I need to retreat the silnylon tarp, or if silnylon has a problem with capillary action? If silnylon has issues with capillary action, retreating the tarp won't fix the problem. If it doesn't, I'd assume silnylon needs to be retreated every so often?
