Glue?
 

So...I need to reglue a powerswitch into a foam plane. The existing glue is white and VERY spongy/jello-like. I can pick it off very easily. Does anyone ahve any idea of what it might be? Secondly, does anyone recommend a certain glue that will behave in this manner? I want to be able to take it off easily. Any help would be greatly appreciated.

RE: Glue?
 

for most of my foamy builds I use Hot melt glue to mount servos etc. Holds very well and could be picked off if carful. If im mounting servos i first cover the servo case in electrical tape and then glue it in place. the tape just allows me to peel the tape off without worrying about globs of glue being perminatly attached to a servo.
