Preserver. Spray, Seal, and Store. 3 can Pack. Inert Gas Preservation System.

Highly recommend this for wine preservation. Works great for a couple of days to a week, depending on yor wine, which is exactly as it is designed to do. I never go without it.

I've saved many cans of varnish, finishing oils, and paint with this. (as well as some wine!) Had a problem with one can once, but the manufacturer made it right. Good customer service!

This stuff works great and you only need a small amount of it I actually called the gentleman that sells it and he gave me suggestions. Wonderful product great service will continue to buy from him

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.

Had this product recommended by the paint store I have done business with for years. They were told to extend the life of held paint to keep from skimming. Recently opened a can that I treated a few years ago and found it to be as I put the lid on then. I was impressed with the results. Decided to stock up for future use. Just be sure to put enough in the can to dispel any oxygen that may be in the can. Since this is a gas the can always feels empty, but it is not. Will continue to use and hope future results are the same as past experience.

I’ve used this product for years and it has saved me a lot of money and headache from paint/liquid degradation! It’s an inert gas that displaces the oxygen in the can. You can go online and read all the information about what it is and how to use it.When you receive the can do not think it’s empty as a lot of people do. The gas is light weight and weighs next to nothing!When using it you place your paint can lid almost in place, stick the extended nozzle inside, press the spray button for a few seconds, then quickly pull the nozzle stick out and close the lid. A few taps from the hammer to secure the lid and you are good to go till next time!!

I use this to protect RUST BULLET paint which normally hardens and becomes unusable after a couple weeks. When used by just puffing a little on top of the paint inside the can. Not sure what other paints that this works with but I would try it if you are seeing quick degradation in the enclosed can. One can lasts a long time.

A bit unnerving when I took the can out of the shipping box and it is light. It does not slosh around like a paint rattle can. It's a gas.Now this stuff does preserve finishes in the can. I use a lot of Min-Wax polyurethanes and hate it when a $28 can skins over after a few uses or thickens to the point it like spreading honey.The can sys it gives 75 uses. The directions tell us to spray a 2 second burst into the can and then quickly slide the lid over. That is exactly what we did. We got about 14 uses out of the can. Well maybe we got a bad can or something. I'll try it again, if we only get a dozen uses that will be the last we purchase this product.
