being a cheapskate, i hate throwing out 3/4 of a $12 can of gummed-up, skinned over sealer.... because I take so long between projects.
I also got tired over putting in and fishing out 1/2-inch steel balls (as space fillers in the original can).
Pipetted into job-sized vials with no air in headspace.
Should keep things fresh until needed.
Ditto with new jar of Chambers finishing oil too. Labeled well.
Stole the foil cap-liner technique from genetics lab people who are anal about sterility and sealing out air.
