Beaty is in the eye of the beholder, the same with Epoxy. What works for one may not work for another.
Research all brands and don't be afraid to ask questions. The first brand I tried out worked for me, but it did take time to learn how to use it properly.
Things to take in consideration:
Is the Epoxy Food Grade Safe?
Will I have an allergic reaction when using Epoxy?
What safety equipment should I have on hand to use Epoxy safely?
