Ed makes an extremely good point regarding compatibility. I ran into that last summer when I took over a mold for some streetrod seats. Fortunately it was nearly 100 deg for a week and I was able to force the cure outside in direct sunlight. It was close to a scrap out however for a while.

I most assuredly would make some tests over the foam and any adhesives used. There is too much work involved here. I would do what I could to use epoxy systems rather than polyesters mostly from my personal experiences. Epoxies have treated me pretty well all things considered. Polyesters have left me holding the gooy bag more than once. (slow learner, haha)

By the way I ran across a single picture of a Connie converted to an early AWACS. I was looking for something else and I forgot where I found it. I'll keep trying.
