RE: sheeting foam with gorilla glue
Areo
See my post directly above yours. Using the poly glue was no different than using epoxy. I've done both now! I started building back in "75" so I've tried a few methods, white glue, regular contact adhesive (melted the foam on first ever foam wing), yellow glue, Mighty Tacky glue, epoxy and now poly. Plenty of time to get things right as far as alignment in the shucks. You do cut your skins oversize don't you? I leave at least 1/2 inch on all sides. Wings came out just fine. IMO, who cares if you get a bit of foaming out a crack in the sheeting. I had one sheet foam through in the middle of the sheet. Must have been a worn hole???? Anyway I know I have a good bond that way.
As far as I'm concerned I just found a new best friend in poly glue. At least in the sheeting department. Oh, leading and trailing edges also[sm=thumbup.gif]
