Interesting that its ability to hold up in the heat was what you liked about MonKote... it sounds like you know how to put this stuff on, which is a skill best learned with limited shrink coverings. In the U.S., where lots of people (maybe most people?) have never used SolarFilm or low-shrink coverings, MonoKote has a bit of a reputation for being bubbly, wrinkly, saggy stuff -- but, again, that's because many people here are relying on throwing the stuff loosely over a frame and hitting it once with the heat gun to shrink it into shape. On the other hand, applied right, it does give a great finish. (A little glossier than I like, but thast's personal taste or lack of taste.)

One of my favorites is micafilm... for gravity powered planes with no under carriage, it's tear resistance is unbeatable and its weight is only about 1/3 to 1/2 of that of MonoKote. It doesn't shrink like MonoKote and it doesn't come with adhesive, so it's definitely more work. For gliders or other places where light and tough are both important, Micafilm's outstanding.
