I've used Oz Cover quite a bit and really like it. It can take allot of heat, more then $kote, but you can still burn it. It will stick and restick numerous times and sticks to itself well.
Surface (structure) prep, as always, is very important, don't want to be doing allot of filling, it defeats the purpose. I used a $kote mit and heat gun and very carefully heated and rubbed the Oz Cov down to the sheeting and cap ribs. It works compounds better that $kote.
I do it a little bit different in that I wipe it down with acetone and scuff it BEFORE I cover. 0 or 00 steel wool and just a quick wipe down is all that is needed. This keeps from over scuffing over the ribs and such but a little scuffing over the seam areas afterward doesn't hurt. For primer I used Duplacolor Sandable rattlecan primer with several coats over the seams to feather them out. If you're good with a can you don't even need to sand (except seams) before color.
I did an experiment by covering a 4"x4" panel with preped OzCov and primed it as described. I took it to a club meeting and the guys tapped it, scratched it, gouged it etc., and the primer would not flake, it was permanently sealed to the covering. Very impressive.
The only other thing to watch is that you use low tack masking throughout because you can lift the film with tape. In areas I've done that I've been able to reseal it with a soft rag and iron, you've got to keep moving. I use dope over it and don't know how other finished would react to the hot rag method, best to prevent having to use it.
I stress again to make sure the entire area touching the airframe is totally sealed down or you WILL get bubbles in the sun. What you won't get is the sagging of other iron-on films. I really like this stuff and the light is plenty strong for a large open bay stunter.
