    You can pick up dry air blanket from barnes. It is an aerosol purging gas. Used it for years on resins and polyurethane with success.

    there have been all sorts of ideas like this going round for years ....... I've come to the conclusion that mostly they are a waste of time and money. ........ or a money make for those selling them.

    For a lot of finish products the air in the top of the can is the least of your worries.

    #1 is the effectivness of the seal ..... so often once you have opened a can and been using it ..... putting the lid back on makes a poor seal. ..... paint tins are a package not a storage container.

    #2 is product ages regardless, even in full tins a large proportion of finish product has a finite shelf life ..... the product will react with its self or otherwise degrade

    #3 tins rust and the bottms fall out.

    #4 some products simply opening the tin signs the death warrant .... as soon at the top is off the product starts rapidly absorbing air and water ....... If you happen to be dipping the brush directly into the tin ..... you are contaminating the product with every dip.

    #5 certain finish products are not reactive and it does not matter what is in the vacant space in the top of the tin ..... add more of the correct thinner and the product is good as it ever was.


    so ..... there is a very small proportion where this whole problem is the problem at all ...... in that case the best choice is to get fresh clean paint tins .... and pour the contents of the part used container into a fresh clean tin that has an unmolested virgin seal.

    cheers

    Most powertools have sharp teeth.
    People are made of meat.
    Abrasives can be just as dangerous as a blade.....and 10 times more painfull.
