I would throw them away and buy some others. Repairing them would be altering a chip. You have a damaged chip and trying to make it undamaged would be altering as much as repairing a drill hole with a new inlay or plastic injection. I am writing this because they are fairly cheap chips. If they would be $5000 chips, I'd say send then to Whelan to repair and take a chance of being thrown out of the club and having all of your friends saying bad things about you.
