Use a needle, toothpick or fine pointed tool to pop any bubbles or gently tap the piece to coax the bubbles to surface. Be sure to wipe any resin immediately from any tools that you use. Bubbles can hide under paper or components. Use a toothpick or mixing stick to press on the paper and components to release any bubbles. Allow to dry for 24 hours. Placing the piece under a task lamp will help the bubbles rise.
