Alright. The title may sound a little ridiculous but I wanted to get some feedback on my idea. I would like to use a stencil (White Tree of Gondor ) and use spray paint to mark both sides of the rainfly. Heres the kicker, I need to find a paint that is not only reflective to see in the dark (my main motivation for this) but it needs to not affect the waterproof coating on the silnylon and also not stick to itself. Any thoughts?? Thanks!
