Glue test, Divinycell H80 left & H60 on the right. 0.8 mm plywood. Great Planes Pro CA kicker on plywood (no glue on plywood). Zap CA+ green on foam. My favorite technique. It seems that when spreading CA over the foam one has the most time to line up the skin your gluing etc, but when assembled, it sets quite fast. Left overnight to set proporly, it sat good after a couple of minutes though. Works equally good with GP medium CA or slow CA's if you need more time = bigger sponsons maybee...
