I like the idea of stealth camping, as I don't like to be an eyesore for anyone hiking nearby, but I'd also like to have a way to signal for help if I need to. I was thinking that the tarp is such a big piece of fabric, it would make a perfect "find me" signal. My idea is to paint big yellow and red circles on the underside of my tarp, so if I ever found myself lost or stranded, I could turn it upside down to display the circles. Otherwise, they would be facing my hammock, and not visible to anyone in the area.
Does anyone have ideas for what kinds of paints or dyes could work on silnylon? I don't want the paint getting all over my other gear, and the slickness of silnylon seems like it would make that a likely outcome.
