I use gorilla for quite a few things, it is verry good for gap filling and sealing and will bond to more substances then TBIII, (IE metal and some plasitcs/rubbers) i however would not use it for any aplication that requires bending. it is very brittle once dry and foams.. its very good glue so long as you use it for its intended applications. I aways have Gorrlia, TBIII, putty epoxy, 5 min epoxy, 3M Weatherstrip adhesive, contact cement and smooth on on hand. everyone is the best glue for something.
