I made an epoxy fill in a tabletop. I used a heat gun to remove bubbles. I still got bubbles on the edges. I saw a YouTube video from blacktail studio about deep pour epoxy table tops where the presentor suggested sealing the wood edges with shellac to prevent air coming up from the wood. I think my bubbles came from the wood that I did not seal.
I am going to leave it alone but do you think it came from the wood?
