Want to know if anyone has worked with precious metals i.e. gold. I know this sounds bizarre but I need to coat the inside of my wedding ring as I have an allergic reaction to the nickel in the gold. Some people coat the inside with nail polish or urethane but it eventually wears through. My wife says get a new ring but I think this would solve the problem. Will there be a problem adhering to the gold and at what temperature does 24K gold begin to melt?:confused:
