I am wondering if anyone else has had the same experience that I am experiencing with this product. It's called Bloxegon (sp?) and by other names. In short, it's a gas that is heavier than oxegon (I beleive argon) and supposedly, you spray a small bit of it into a container of paint, varnish, urethane, etc and it settles to the surface of the finish and blocks oxegon from curing the finish to a surface "skin". In effect, preserving the entire remaining contents of your finish for future use. Well, I had purchased a container of Bloxegon a while back and I got nowhere near the life out of the can than it says on the label. In fact, it didn't work that well while it was still an active can. I figured that I got a bad can and I ordered another of the stuff from Lee Valley. Same identical can, but under the Lee Valley brand with their label wrapped around the container. Fresh can....... (two or three three to four second bursts of its contents old) into a quart can of wipe on tung oil and poly combination and I opened the can today and there was a slight skin on the surface. The stuff isn't drastically expensive, but it isn't cheap either. The idea is a good one, I just want it to live up to its claim. Has anyone else had this kind of experience?
