Sugru is a self-setting rubber for fixing, modifying and improving stuff. It molds like play-dough, bonds to almost anything and turns into a strong, flexible silicone rubber overnight. It comes in several colors, and is great for all sorts of things.
If you've broken your jacket's zipper pull, or just want more grip for it, Sugru is ideal.
Sugru in the desired colors (You can mix colors if you like!)
Step 1: Open the Sugru
The Sugru comes in little metallic packets to help keep it fresh. There's dotted lines on each packet showing where to cut the packet open. Go ahead and cut open these three sides, peel the packet open, and scrape the sugru out.
Step 2: Knead and Mix the Sugru
Knead it up for about 30 seconds to get it activated. This is a good time to mix up different colors! Your working time with Sugru is only about 30 minutes, so don't take too long.
Step 3: Divide Up the Sugru
Divide up the Sugru however you need for your zipper pull.
Step 4: Shape the Sugru and Let It Cure
Put the pieces of Sugru together on the end of your zipper pull.
Wait 12 hours, and it's ready to go!
