So I made a tumbler months ago. It looked fine, and had no major defects although it had some small air bubbles but nothing too big. The edges were all sealed on the cup. It is hand washed only and hasn’t been in extreme temperature change or humidity. Today there’s a spot on the resin that has changed cloudy. Months after it has been made and cured. Can I fix it at all and if so how? Does anyone know what may have caused it to happen in the first place? This is the only one I have made that has done this.
