I've looked at a few projects and finished RV12s to get a better idea of what Van's has in mind with this process (in addition to reading the directions, of course) and the new epoxy pumps arrived from Aircraft Spruce this week, so I went ahead and bonded the foam blocks to the canopy frame with epoxy. I laid a couple of 2x4s against the to exert a slight pressure to be sure they bonded well. Not sure when I'll get back out there to start sanding them into shape.
