Hi converts; I've just started reading this episode about the fabric covering and the methods utilized to seal the weave, it dawned on me that some time ago the wife and I had a small shop on which we made baseball uniforms, jackets, banners etc. and one of the fabrics that we used to handle was a "light weight nylon" that is similar to the linning polyester, but this nylon is "ALREADY SEALED" because its water-proofed and it will heat shrink, it is similar to the nylon you will encounter in a wind breaker jacket, wind-sock or some flags for that matter; I will check and see if I still have some left over and do some testing; I think It will be heavier than monokote but if you want to try it?, the covering material that I am presently using is the 2.5 mm self adhesive vinyl (bumper sticker material) which you can purchase in a sign's supply store I personaly like it because 1.- is cheaper than monokote, 2.- it's easier to work with, 3.- you only need a heat gun and 4.- there is an ample array of colors and design patterns to choose from. Oh and one other thing "its paintable" try it for once and you will fall in love with the way it handles
