I have a bubble in my cured epoxy a little bit smaller than a pencil eraser. How would a fix this without having to sand and recoat the entire project?
You can patch, but be aware epoxy only sticks and does not dissolve into the surface like polyester resin. So, you may, or may not, see a hairline at the edge. A patch is worth a try as failure only puts you back at square one.
