I'm looking at a sign that appears to be in fantastic condition, one small chip. It's described as "some clear coat". My main question is: "Is the primary reason to clear coat a sign to make a dull porcelain surface brighter and shinier?" I have one sign that has been clearcoated but it was also restored. Additionally, if there is only clear coat on a porcelain sign can it safely be removed without any harm?
Thank you for your input,
