Epoxy is generally used to cover enamel to give a glossy look. It also adds protection to the paint. This is an option we highly recommend. It really helps the color stand out. Epoxy has a rounded feel and look to it as it is applied after the coin has been painted.
Colored epoxy is also available. Why use colored epoxy? Because it’s different and can really set your coin apart. Instead of using blue enamel for water, why not try blue epoxy. It almost looks like water! The sky is the limit with your custom challenge coins, think outside the box!
