If your sign is going to be outside you will need a quality clear coat or it will fail. If it is going to be indoors most any spray can clear will work. I spray can cleared this sign. I like that it is not too shiny. It does not look like it has been clear coated. It did bring back most of the color. It had a faded chalky look to it.
