Lacquer Thinner Rejuvenates Wood Putty

If you have solvent-based wood putty that has sat too long in the can and now is as hard as concrete, all is not lost! Don’t throw it away. Instead, add a little lacquer thinner to the can and leave it for a couple of days. It’ll soften the putty again. Then mix it up thoroughly, and the putty will work as good as new.
