I used thin CA to glue a piece of wood for the antenna straw. The CA dripped out and totally melted the styrofoam on both sides of the fuse down to the sheet. Yes I should have used foam safe CA glue. I know that now.
There seems to be no good answers from other forums on how to repair/replace styrofoam on the inside of a fuselage.
What type of glue? What techniques?
FYI: The styrofoam is the beaded type that looks like small b. b.s that are pressed together.
