Larry,
I have a set of pristine wings that came with this project with Diehl
skins on them. Don't know what was used to put them together. Would
it, in your opinion, be worth trying to 'heat treat" them, not
knowing the epoxy system that was used? I wouldn't anticipate that
the 150 degree would hurt them...........Bobby
