I know it has been awhile and the topic has been covered to death but, I just read a post on the web, comparing weights of covering materials, and the Monokote Red was compared. In 1971 it weighed something like 7 grams per square foot while the red in 1996 weighed in a 5.8 grams. Someone needs to explain to me how it has not changed. To me, it is not consistant from roll to roll and even in different parts of the same roll. I have seen posts here on RCU where someone is extolling its use and showing pictures of his work and I can see wrinkles in the small pictures. I do not like the stuff, the learning curve is high and, unless you cover frequently it seems you are experimenting all over again. I will say that it works pretty good on open framing (wing) but not so well in other areas of the same plane (sheeted surfaces). I have been in two clubs and looked at many covering jobs and have yet to find one with no wrinkles or saging......maybe I am too particular. Do a Google search for Monokote, its about 6 pages deep. It is a usefull post. I will try and find it in my history and will post it if I can find it. Found it ...http://www.fatlion.com/sailplanes/weights.html give it a look.
