    I recently read a post about using Butane ( I think ) to flood the open container and displace the air prior to replacing the lid. I can't find the thread and I hope someone can give me the correct info on this.

    Why not just ask for extra can's at the paint store? that's what i did never a problem and usually they just give you the cans free.

    Punch a hole in the lid near the edge with a screwdriver, and a smaller hole opposite for air. Seal the holes with tape immediately after pouring some into a smaller vessel; use or discard what you poured out. It will last much longer.

    That's what I've been doing and the stuff skins over and I end up having to remove the lid to get the skin off. I thought the idea of using a heavier than air gas to remove the air would prevent/ delay the skinning. Thanks for the reply.

    Propane is heavier than air too.

    I wasn't sure of that; so that's worth a try. What about Argon? Anyone know if it's heavier than air?

    I use a sheet metal screw in the side at the bottom. Take out the screw pour what u need in a seperate container then put the screw back in. Had the same qt can for a couple years

    i saved mine by taking Saran wrap and pushing it down inside the can on top of the paint forming an air tight seal directly on the POR

    I've had good success with that method, too. Don't forget to use new Saran wrap every time you re-open the can.
  12. The screw in the bottom works good because you're not allowing air to enter.You have'nt opened the can!

    You are spot on with the Argon......Any inert gas will help with the skinning.

    Good info! I payed $40.00 bucks a quart at the swap meet and maybe will only use about half. Good stuff ain't cheap! I will seal & store as mentioned.

    I knew you guys would have some good ideas. Hole in the bottom and plug it with a screw. Too simple ; I have to try it. Thanks to all. Joel

    I seal mine, and put in a small Refrigerator. That is what Company advised me to do, over ten years ago. I now use KBS, easier to work with. they have a lot of new products coming out also.

    If air doesn't get in, how does the paint come out?
  20. I use argon also. I have the stuff in a glass jar with a lid that I just poke holes in when I need to pour some out. Fill a little argon in and tape it shut with aluminum tape.
  21. ============================================
    I see this is a very old post. .........Here is a product made to extend moisture sensitive products. I use this all the time.

    Inert Blanketing Gas

    This will also put a blanket of Inert Blanket over Gas
  23. I bought a quart a couple years ago... mangled the lid getting it off. I used a little, no way the lid was going back on. I poured the rest into an old spaghetti sauce jar and put it in a cabinet in the garage. I needed some last month, opened the jar. No skin, it was still perfect.

    I purchased a quart at Hershey and when I went to use it a week later I had to cut the top off. No matter how many screwdrivers I used, I could not get the top to come off. I totally mangled it. After I used it I stored it in a plastic jar with a screw on lid until I used it up.
  25. I guess the lids got a little of the product on them before being smacked home... says something about the product, tough stuff.
  26. I have never used this trick with fancy paints or plastics, but on many occasions, after using a small quantity of paint out of a large container, I have filled the original container with good sized, clean rocks, to displace the air from the paint. I have used this technique successfully for over 50 years.
