Some time back Bill Wilson and I were talking about how to keep model glue/cement from attacking foam, and the suggestion was made to put a coat of alephetic resin (yellow glue ), let it dry, then try some glue on that and see if it attacks the foam, so I gonna try it...
What say y'all 
If done properly, that will work fine. I did something like that for a science fair project that involved laminating 1 lb white foam into a block 5" thick. Even at the time (which was about *40 years ago*, to my astonishment) I knew that you couldn't just glue it together with Titebond and have any chance of it curing. Failing to find any water-soluble contact cement around central Arkansas in the 45 minutes we looked, I coated the foam on both sides with a 50/50 mix of Titebond, water, with some Knox gelatin (per Ron St. Jean's "Structureless foam composite" article), and let it dry. Then used regular solvent-type contact cement.
This project required taking this blank of 5" thick and about 3 feet in diameter, and turning it on an ersatz faceplate lathe into an aerodynamic shape. We just took after it with various tools like woodturning chisels and Surform tools, and eventually sandpaper. I guarantee you that if you go into the garage of the house at 1410 Lenore Street, Benton, Arkansas, and look around in the corners, you will still find white foam beads floating around in there from this effort. The single biggest mess we ever made.
