Bloxygen Preserver with Plow and Spout, 2 Cans 0.41 oz. of 100% Natural Argon Gas, Inert Gas Can Preservation System for Paint/Auto Chemicals/Varnish/Food & Wine Preserver, Home Improvement

Excellent product. Has saved me tons of money in finish that would otherwise have gone bad. Spray a little into the finish container. You don't have to displace all the air, just enough to create a nice layer of the product between the finish and that air. I don't know if there is a time limit to the protection it provides. If there is, I have not found it.

I have been using this to help preserve mead, and it works very well. You get more than you think with how light the bottles are. It was worth it all around.

I was having constant issues with wood finishes like Rubio and OSMO skinning over in the can after opening. These products are expensive and it's a waste of time and materials trying to remove the film before use. This gas displaces the ambient air in the can and now each time I open the finish it's ready to go!.I simply use the finish and give a quick shot of the Bloxygen gas into the can before closing. It's pretty remarkable. I bought the two pack and it will last a while since it doesn't take much to do the job. I've found a quick burst is enough. It's also gentile enough that it doesn't splash the finish or make a mess.What I like:1. It's easy to use and keeps the finishes fresh. I'm able to use the entire container of finish without waste. I used to break the larger can into smaller containers to reduce waste. That's not needed any longer.2. Two pack is more affordable and will last much longer.3. Can be used with paints, urethanes, or any material that is at risk of hardening in the container.What I didn't like:1. The can feels empty! It's not, there is plenty of the gas in the can, but it feels empty and can be difficult to tell how much is left in it. It's likely due to the nature of the material (it's not like other aerosols) but it still feels odd. I got over it because it saves me so much money in wasted finishes.

it works great

This stuff has saved me hundreds of dollars by saving what is left in the cans for later use. Buy some!

It doesn't seem that it would do what it advertise but I had paint at least 4 years open it and no skin just stir and use

this is a joke not a good buy find a welding shop // better off //

I've been using this product for years. It works as intended. I'll admit that the weight of the cans is a little unsettling (they're super light), but rest assured the cans are full. I use this for finish preservation and to keep the bourbon collection from oxidizing.
