Just back from wild gorgeous green steep wet Dominica...
I experimented with a few products. I have tossed the cans, but I do remeber that the Great Stuff was of the triple expanding kind. I do belive it was the space filler. You want the one with the most expansion, otherwise you end up using many cans. 3-4 cans did the job for me.
I also had success with another brand called "Space Invaders", which was some great green wellexpanding foam. However it took a while to dry.
I am planning on making an impoved version of my case once I get unpacked and settled back to reality. Planning on taking and posting some pix ... and recording exact wording on foam cans for the benefit of future experiments
