Review (4/5): Don't forget to tap it!
I tested this product by attaching a metal pocket watch to my hand and let me tell you, it's been on for two hours so far!
When using this stuff, you really have to make sure you tap the spirit gum until it's tacky. If you don't do this, it won't stick to your skin. The more you tap, the tackier it'll get, and the better it'll adhere to your skin.
