Seeing that you are going to be using Lawrence Welk's mirrored ball, you
should also attach his perpetual bubble machine, and use it for thermal
location.

We had a real blast yesterday tossing out rolls of toilet paper
and slicing them with the wings. Also seemed good for thermals.
Harder to see than a glider though.

There is reflective tape that I've used before on boats...
