Bloxygen Leftover Finish Preserver

Bloxygen displaces oxygen and moisture to protect and preserve leftover paints and varnishes. It prevents wasteful skinning over or thickening in the container. Use it to extend the shelf life of leftover fine finishes, oil based paints, oil based stains, varnishes, paste wood fillers, polyurethanes, resins and glues.

Bloxygen uses ultra pure Argon, a heavier-than-air inert gas to block oxygen from liquid surfaces. Simply insert the straw into the cracked lid, blow a short burst, then immediately seal container. Oxygen and moisture is displaced in the open spaces by a protective blanket of heavy gas. A single can will work about 75 times in quarts (2 second shot) or about 35 times in gallons (4 second shot) so less than 15 cents will save a $20 - $50 product.

      Comments about Bloxygen Leftover Finish Preserver:

      This stuff actually works. I guess the Argon is heavier than the oxygen and forces it out of the can. When you come back, even after years, my varnish is as fresh as the day I left it.
