Epoxy Resin is a great material to use for projects that require a “clear” finish.  There are many brands and mixes of material to use, and different techniques allow for different outcomes.

These processes require a lot of testing to ensure that you have a great outcome.  Bubbles in the epoxy are a big problem.
