Hi, I'm just rebuilding a foam wing and don't have any "foam safe" glue could I use epoxy without damaging the foam too much?

Epoxy is foam safe, but it will add quite a bit of weight if you are not careful

Ok, thanks, shall plow on.

One of the best glues for foam is Polyurethane or better known as Ultimate, Nano, Gorilla. The foaming action really penetrates and grabs well.

I have allways used 5 or 10 minute epoxy on foam with excellent results.

Just don't use CA. Ask me how I know !!!

I'll add in an endorsement for gorilla glue if you are looking for something between epoxy and CA. It is really tenacious, expands in gaps, and personally, after having a motor mount fly off after extensive CA-ing, I've switched over to gorilla glue for those very high stress areas and haven't had a problem since.
