Hi,
Has anyone here experimented with using a Vac U Vin for storing finishes? I'm talking about the plastic device that looks like a mini plunger they sell for wine aficionados to suction the air out of an opened wine bottle to allow the wine to last a little longer. It relies on these inexpensive grey stoppers. Since the thing creates a vacuum inside the bottle by manually sucking out all the air I thought it would work for preserving finishes, especially oil varnish finishes that can skin over and start coalescing. The stoppers might fit empty beer or soda bottles if wine bottles are too large for storage needs. I tend to prefer more smaller containers for storing finishes.
If this has not been tried yet, I will give it a try and report back. Didn't see mention of it in the archives.
