Lancaster Archery TechXPert Dan Schuller talks about the archery applications of Sugru. Sugru is a glue that turns into rubber after it cures. It's flexible like play-dough when you pull it out of the pack, so you can mold it to fit the shape you want. Let it sit exposed to air for 24 hours, and it will stick wherever you put it. It also will retain the shape you set, but will feel soft like rubber.As Schuller explains, Sugru is perfect for customizing your bow grip. No two hands are the same, so no mass-produced bow grip is going to fit everyone the same. With Sugru, you can build up sections of the grip to fit your hand.
