You might try a hair dryer first, as that will let you heat up the material and smooth it out with maybe a book or something heavy, without risking melting the silicone or fabric.
Sounds right, but all those people who complain about sil-nylon stuff getting all saggy after it is rained on can't be totally wrong. I have also heard people complain that they get a slight bit of spray through a sil-nylon tarp in heavy rain.
I'm no expert, though. I have exactly one piece of gear made of it, and have never used it overnight.
