Reading through the thread on shellac mixing I came across a post by Edward Alexander mentioning his use of Mason jars. (Here) I use these jars (mine are the newer form with the metal caps) for everything including shellac, brush cleaning, etc.
Recently I purchased a Food Saver for my wife and I got her the attachments for vacuuming out and sealing Mason jars. While reading Alexander's post it occurred to me that I could be using the Food Saver to prolong the life of my finishes and it would cost a lot less than Bloxegen!
It seems to me that transferring varnishes, shellacs, etc. from partially full cans to Mason jars, then removing the air, makes a lot of sense. The parts of the Food Saver that vacuum out the air never touch food, so that should not be an issue. And I have no problem with buying a new Mason jar attachment for using only on my stuff.
Am I missing something? Is this a good idea or what?
