Why does my resin have tiny bubbles?
Porous, organic materials like wood, leaves, fabric and even some soft, lower quality papers contain air and moisture, which they absorb and emit depending on the climate. This is called off-gassing and it results in air bubbles in the resin, sometimes hours after you have poured and torched.
Why is my resin not shiny?
Foggy resin projects can happen for a few reasons: Make sure the mold is clean and completely dry before pouring. The mold can play a part in the finish. If the surface of your mold is shiny, the resin will be shiny. This silicone mold is very matte, therefore the resin turned out dull and matte.

How do you make sanded epoxy shiny?
Use a buffing wheel (or any polishing tool) to polish a larger piece of resin. It is best to attach the buffing wheel to a power drill so that the process is easier. Apply it as evenly as possible until the resin is shiny and smooth. Rub the surface with a microfiber cloth to get a glossy finish.
