There an how to a couple of years ago in MA about sheeting big wings. It said to put the epoxy into something you could squeeze it out of and make crossing lines with it. So you'd be laying beads about an inch apart, then come back in the other direction. The reason for it was to save some weight, and since the epoxy squeezes flat when you put the weight on it was just as strong. Using this method kept so much from being absorbed by the wood, so the theory goes.
I saw that too, was looking for the article. It was basically a honeycomb job, without removing the foam and making it fragile.
