I just recently switched to ArtResin epoxy for my tumblers. Since then I Have not been able to get the bottom edge of my cups to cover smoothly with epoxy. The very bottom will cover. And the wall of the tumbler. Just not that edge connecting them. I tried adding more resin to the wall and pushing it towards the edge, however that just leads to it bulking up as a wave right before the edge.
Do I need different epoxy? A different technique?
