Evaporation and oxidation begin when you first open a can of finish, and each time you open the can it gets worse, eventually rendering any remaining finish unusable. Transferring the finish into one of our StopLossBags™ and squeezing out the air means the finish can be used to the last drop. The easiest way to transfer finish from a wide mouth can is to use the StopLossBags™ Funnel. The special flexible material will stretch over the opened can and the mouth of the bag which means almost nothing to cleanup except the funnel and that’s easy. Allow varnish to dry overnight and it will easily peel off the funnel.
