Well actually I want to fill holes slightly larger than pin holes but both apply. I don't have a pressure pot and sometimes fill larger cracks with epoxy. I often get bubble holes sometimes as large as 1/8" or so, often smaller. I have with some success filled them with thin CA but it always shows a slightly different color. I've tried filling with the same epoxy but the surface tension may be the problem. It looks like it fills it but it's only surface deep and when you shear scrape to level the surface the bubble comes back. Sometimes by poking at it with a thin blade I can get enough penetration to fill it. What do you all do. I usually manage to get them filled enough to finish a bowl but it's always a fight. Any advice. I'm wondering if there is something I can add to the epoxy to reduce the surface tension and get it to flow into the hole. Not sure that's the correct term but I know a water droplet will sit on top of a small hole unless you add a detergent to it and then it will flow in. That's why I used the term surface tension. Don't care what it's called just want to find a solution.
