So like the post says I just got my first sil nylon tarp. So the thing is I'm really not sure if there's anything I need to do to it before I use it. When I first got my tent I seam sealed it. Do I need to do anything like that to the tarp ? Also when packing or storing it do you fold it or just smush it into its stuff sack ? I know there has been lots of discussion about how to store tents on account of making creases in the material. Is sil susceptible to the same thing?
