When I was doming a piece of resin I used the wrong ratio of resin and hardener so now my piece is sticky. Is there anyway to remove the sticky resin or is the piece ruined?
You can try soaking in acetone. You may be able to get the resin to come out. I have also heard some people have had luck boiling their pieces, then removing the resin. (Once you use implements for resin, do not use if for food again.)
