fireproof mylar blankets?

at my local kmart they have safety fireproof blankets of mylar, for camping this is the shit i need rite? also for anyone who was lookin go to any department store and look in the camping shit, it is really inexpensive this way.

Sorry, Mylar is too technical!

Just use flat white paint, it's the cheapest, and easiest way to reflect light.

I was thinking the same thing. Did you try it? HOw did it work?
