Cannot guarantee it'll be a perfect fix, but: skateboard deck tape. I applied it in the past to metal brake levers on my mountain bike, the adhesive stuck well. A foot of it is way more than you need and should only cost a few dollars at your local skate shop, they may have different 'grit' levels, so check when asking for it. Worse case: contact cement and emery cloth. I'm about to do this to my Enertia+.
