Patrick,
What a great idea. Nicely done.
As too a tougher film, I can think of two alternatives:
In the R/C aircraft world, built-up wings are frequently covered with
Monokote, a heat shrink film that comes in solid colors, transparent,
metal flake, etc. I'm quite sure it would be more tear resistant than the
window wrap.
An even tougher film is "boat shrink wrap," the stuff that's used to winterize
boats. It is really thick and tough. So much so that it might pull a wheel
cover out of flat if you're not careful when shrinking it. The stuff comes in
white and clear that I know of, but you rarely see the clear. Hopefully you
could paint this stuff with one of the new plastic paints in a spray can.
Right about now folks are thinking about winterizing thier boats. Some are
getting a early jump on the process so boat shrink wrappers may be at work
in marinas near you. If you ask around you may be able to pick up some
scraps or buy the small amount you'd need.
Google "boat shrink wrap" for more on this.
Good luck to you.
