I think we used to call that stuff "FASCAL" and covered C/L Combat planes with it. It's amazing what the sign shops are able to do with that stuff.

Some guys are using craft store cellophane misted with 3M77. It needs very low heat to shrink, but it is very flimsy [and light]. The thinking is that C/L combat planes don't have a very long lifespan win or lose, so might as well do as light a covering job as possible to increase your chances of winning. At least that sounds good in theory.
