If you have a tig welder use the 100% Argon.
.
If you do not have a Tig, use Bloxygen or similar Gas blanket.
"Bloxygen " Sold on Amazon and other vendors Still a must to to clean the can top and and sealing rim. Or you will not get the top off after drying.

What about shooting some Mig gas into the can just before popping the lid back on?

 

I have never tried it........
I would think to should be ok .. It can't be any worse then using nothing.
.

. I use the spray can with the little tube. I punch three small holes on one side lid near the edge, and two on the other side. Pour out the needed paint, tape over one set of holes. Then spray two/three seconds of blanket gas, then tape the remaining holes. I have shelved cans for several months.
This is what we do when products sensitive to moisture. such as Brake fluid any paint.

The reason I suggested mig gas as it is inert so it does the trick.

 

Craziness. Just use two self tapping screws in the lid. One to pour out of and the other is the vent. Keep the cans in the refrigerator and they last for years. No fancy stuff needed

 

I only buy pints, and use it all at once.

 

I put 2 pieces of saran wrap in between the lid and can. Hasn't failed me yet.

 

Any unused POR after I open a can gets transferred to small plastic cool aid containers.
The plastic containers are flexible and easier to get open. If the POR skims over in the container I can easily remove the bad material. Clean up is also easy using lacquer thinner.
I found I get a longer shelf life by storing the leftover POR in the refrigerator. Recently I used some that had been in the refrigerator over a year.

 

Easier than all this. I just turn the can upside down after sealing to store it. Air can't get in if it's blocked from the inside with the product. Been doing this time after time with Por 15 and all paint and stain.

 

This works.do it myself.
