Seriously, you can use it on wood, ceramic, plastic, glass, etc. For more details, including a Glue Guide and a VIDEO demonstration of using it to repair a wobbly chair, go to www.gorillaglue.com
Website indicates it can be used on metal (CHECK OUT the WEBSITE) - it does NOT act instantly like Super Glue, it takes awhile to set and two pieces must be clamped together while the glue sets (hardens). Tell you what - just let me win it......LOL
I took an old dresser that was falling apart and put it all back together using Gorilla Glue... It works AMAZINGLY WELL!!! It's a must have for anyone who makes repairs...even better than duct tape!!!
