Foam wings question
The new 3M-77 does eat foam.....
I build alot of giant scale airplanes for other people. I wouldn't even think of using ANYTHING but PRO BOND or GORILLA poly glue. Spread it on very thin and it "FOAMS" up to fill voids and create a perfect joint. Using the POLY GLUE allows you the capability to NOT edge glue your sheeting, rather you just simply tape it together and you're ready to go.
