John,

The application of heat, a little more than the average hairdryer delivers,
both shrinks the film and activates a quite powerfull adhesive that is on
the underside of the film. The adhesive is strong enough to remove the
surface of underlying balsa structures when trying to remove the film to
repair an RC model..

I'll have a word with Jim Hammerton and see if he'll let us try it out on
the Ventus ( which has some surface cracking )

To take Bill's point further, if the film could not
be shape changed somehow then there is no way you could
get span length roll of film to fit tightly to the
curves of a glider wing along its full length.
