The differences really come down to weight and ease of use. The heavier stuff, Polymicro, Ultrafilm, and Superultra film are all fairly easy to work with and do really well in events like Limited Penny Plane and Science Olympiad. The thinner and lighter stuff, OS film is half the weight or more than half the weight of the heavier films, but also more delicate. It is also useful in LPP as you can put the saved covering weight into the structure. OS is honestly good for all of the classes that allow plastic for the above reason. If you can save 25+ mg of covering, that is more wood and strength you can build into the structure. The other types of film you might hear about are the now near unubtanium Y2K and Y2K2 films. Used originally as a test material for military grade capacitor insulation (at least that's what I was told), a relatively small amount of this film was produced. Many in the cm unity new it wasn't going to last long and bought several rolls, which the use sparingly still. Lighter and thinner than OS (at least the 2K2 is) this stuff is great when you need the lightest covering possible. Great for micro light EZB's, and to replace microfilm in F1D and HLS. The OS film and Ultrafilms are easy to get. Ray Harlan and Hobby Specialties sell the above. You will have to have to either sweet talk or pay lots to someone with a private stash of Y2K/2.
For application techniques, INAV has some articles, but a really quick way to find them is on www.indoorduration.com. There exists several articles on covering with the plastic films.
Hope that helps, and feel free to correct any errors you all see. Not being around when a lot of this stuff was being used, I am going by hearsay and stories.
