Gorilla glue

From CosplayWiki

Gorilla Glue is a brand of multipurpose polyurethane adhesive. It can be used for both indoor and outdoor purposes.

Before application, a small amount of water should be used to wet either one or both surfaces as water initiates the curing of the glue. It should be clamped for at least 3 or 4 hours to cure, and for best results it should remain clamped overnight. Once cured, it is waterproof and can be sanded. It should be stored away from direct sunlight, and in a cool dry place.
