some times grinding a polishing is the only thing to do, but Most of the time you can repair them to look like they did. below is a before the grind picture
Wow, nice job with the repair. I have always wanted to do repairing on bottles but am not sure where to get the right epoxy and how to make it match the color of the bottle. I have the equipment to grind and polish it then. Can you give me some advice on what to buy and where?
