I have not experienced (as far as I can tell) expansion after the initial cure, using the GP330 light PU-foam.

But someone told me the other day how some time ago he bought a Destiny when he was learning to DS, and drilled big holes in the underside of the D-Box area, and filled it with light PU-foam till it came out the vent holes. It didn't expand the skins at the time but a week or 2 later he noticed that the skins had bulged out a bit. But in his words "But it still flew GREAT, and man that thing was TOUGH!!! And I flew the living daylights out of that thing for a long time too!" (it was Bruce Tebo and knowing Bruce I'd say that plane did a lot of flying!!!)
