Preventing copper tarnishing

Is there a clear coat that can be used to protect a copper coil from tarnishing? This clear coat would need to be a coating that would not chip, flake or discolor in time. Please suggest the best solution.

Before you can decide the process, the production volumes are important.

For very large and regular volumes, Clear Electrocoat is a great option. It is available in low and high build depending upon the trade off between clarity and durability.
