Bobby,
The Diehl skins use Vinyl Ester, and I do not think that you need to treat
them. These skins will hold up quite well as they use a high density 1/4 inch
foam core. I think it is Clark foam, but not sure about that.

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
