Richard,

I like your idea of using the 3m tape spaced out to help keep from squeezing out too much epoxy. I was concerned about squeezing out too much epoxy when i clamped them in place, especially as the skins seem to be slightly bowed on their own. So when I clamped them flat, it probably did squeeze out too much epoxy in places. My surface prep was similar to yours, except i used very rough sandpaper on the last step to rough up the surface.

Do you recall which of the 3m double side tapes you used (or thickness of tape)?

I'll try the Thixo as well.

Thank you,
Alan
