Patch the tube: The last step is sticking on the patch. Hold it by the cellophane and peel the foil off to expose the patch's sticky side. If the foil won't lift, try pulling from a different edge. Now, press the patch on the tube making sure the hole is in the center of the patch. To finish the job, roll your pump end over the patch to fully seat it (photo). Don't remove the cellophane as it keeps the patch/glue from sticking to the tire. Good job. You've recycled your tube!
