If you’ve worked with resin you know that it can be tricky to get a mirror-smooth finish. You’ll see and feel all forms of imperfections including pits, bubbles, waves, and bumps. You’ve seen a smooth finish in resin, however, whether it was in an Instagram photo, video, or a piece that you saw at a local craft fair. So you know that it’s possible to achieve a smooth finish, but somehow it seems out of reach in your own shop.
