Bloxygen Preserver. Spray, Seal, and Store. 1 can Pack. Inert Gas Preservation System.

This is a great product that I have been using for years. I spread it in my cans of paint and varnish and it keeps them from skimming over or going bad. It also works great in my home deep fryer to keep the oil from going rancid. I just sprayed it over the oil or in the paint can before putting the cover on. This stuff works great. It keeps me from having to drain them and wash my deep fryer after every use I would suggest getting a couple of cans because the only downside of this product is you can’t tell when you’re about to run out. The can feels empty whether it’s full of product or not.😂

Is canned inert argon gas and works great to block air from contacting liquid contents of polyurethane, etc. Don't be concerned when you get it that the canister is so light it must be empty- the canister is very lightweight aluminum and the gas is virtually weightless so it just feels empty.

I have been using this product for years and it works beautifully! It saved me a ton of money over those years.

This stuff is not perfect, but it definely helps. I use a gallon of high quality spar varnish for teak on my boat each year. Cheaper varnishes don't skim up. Good varnish does. I have opened and closed the gallon can at least six times this past month or two. The first couple of times, there was no skim. I kept the can open briefly, poured a small amount, then with the cover pretty much closed, I sprayed the product in. Then I closed the can and tapped the top shut. Once in the process, there was a fair amount of skim, but most of the time, there was no skim. This is worth a shot. I will use it again.

A must have for saving paint and varnish! I use this every time I close a can of varnish and I never lose cans of finish when I use it.

My husband says it did meet his expevtions.

Not able to use for what i intended and cannot return per amazon.

Pleased with price, speed and quality of shipping. Appreciate they package this product in inexpensive containers! I plan on buying more! And yes the can feels empty, but it's supposed to, it's a gas!

No good it doesn’t work. Expensive for nothing.
