I have been using Gorilla Glue for a while now.  Things to know:  You must moisten one side of the parts to be joined.  This adhesive is moisture activated. A spray bottle set to a fine mist does the job.  Monkey glue (generic for polyurethane adhesives) expands so the joint must be clamped.  It has the wonderful capability of expanding to fill poor joints such as a loose fitting wing into fuselage.  I have come to like Elmer's brand over Gorilla Glue.  Gorilla Glue will STAIN your fingers brown.  Elmer's not so much.  Elmer's does not seem to expand quite as much which can be good.  I have even used it for wing fillets!  I just had to babysit the glue as it began to expand and then wipe it off several times until it quit expanding.  It is good for laminations, not good for ribs to the LE.  What I have seen so far is that Gorilla Glue is so sensitive to moisture that it almost needs to be stored in a vacuum or you will lose half the bottle.  Again Elmer's is less sensitive.  As long as I replace the snap on cap right after use I have been able to use the entire bottle.  Note to the wise: always buy the small bottle.  Any product you use that is new to you will take a bit of learning.  This is good stuff is used properly.

I keep mine in a jar with a desiccant.  I keep the CA there, too.  It's a trick from Iskandar. 

I wear gloves when using Gorilla Glue. 

Another virtue is that it doesn't dissolve polystyrene foam.  It's good for fixing foam combat planes. 

Golila glue is a great substutue for epoxy if you have issues with toxicity.  It is number 1 choice for working with foam.

For repairing foam, you can inject it in a crack with a syringe, cover the crack with packing tape and the foaming action will take care of the rest. 


Not the kind of stuff for making filets, but good for sheeting and large surface area jobs.
