Hi Linda Try contacting: 3M Corporation (800) 364-3577 for their official answer Leslie > Hi, Conch-Lers! > > I am still on a natural high produced by all the enjoyable people and shells at the COA convention, but I have a question. > > Can one remove 527 glue from a shell with acetone? I have used acetone before and know it will not hurt the shells. > I am back to trying to attach my little plastic numbers to my shells, and clear nail polish does not work - or at least, I can't get it to work so far. Remember that I have no way of printing the numbers small enough by hand or computer printer, so I am using "Shrinky Dink" to make numbers small enough for my cataloguing. > > Thanks, > Linda >
