rajul I'm still using some that I opened 10 years or so, if I need to thin it I add water, just don't leave the cap off.
banktoturn I us Gorilla Glue a lot,go by the directions ,and be thrifty,the glue expands as it cures,fills cracks and voids,on butt joints it can expand and seperate the parts,also easy to sand and cover over,it will not replace all other glues but does have a place in our building especially on wood/foam,such as wings.
Have a goodun,John.
