I do the holes around the rim trick plus i usually strore the cans
upside down once I am sure they won't leak. Alkyd enamel gets that skin
which is always a pain in the ass.
The gas you want is nitrogen. Usually sold at auto body supply stores
because the catalysts for urethanes will go bad very fast without a shot
of nitrogen once they have been opened.
One Surge Cola fan (http://www.savesurge.org ) suggested a long time ago
moving pop immediately into smaller containers if you weren't going to
drink it all. That would help keep the carbonation in. Simply
compressing the container would not.
Just putting my 1/50ths of a dollar in.

You don't want to squeeze the air out of plastic carbonated beverage
bottles, because it's the pressure that builds up in the container that
keeps the carbonation in. If you squeeze all the air out of the bottle,
you're giving the CO2 a lot more room to fall out of solution and make
your drink go flat. There are products for carbonated beverages that
actually inject CO2 into the bottle and repressurise it, thus helping
keep your drinks fizzy.
Almost all my cans are upside down now, and it helps, b/c I think it
dedfinitely limits corruption to the air contents of the container.
Latex/oil, o/, who knows: this may be something that could be a solution, if
only I could remember which, anyways. But there is still corruption inside.
The liquid contents stops more air from geting in. When right side up, no
matter how clean your can is, air gets in and out. But a can near empty of
air helps. Doing both is prob best, and only need lose a fraction of the
total, and little scraping. I just need best containers with seals that can
be cleaned, or maybe just lots of them. And how to seal them best. Then if
its unlimited maybe it would be worthwhile
Two kinds of glue, silicone RTV and polyurethane (Gorilla Glue etc.),
water-catalyzed. So they keep fine in a DRY environment. A paint can
some dessicant (I used lab dessicant, CaSO4 type) can make a storage
environment for long periods. That paint-can seal is rather good (buy
a new paint can, though; my used paintcans never look particularly
Once I took a knife to the side of an RTV tube (after the tip cured
and scooped out what I needed. Popped the remnant, gashed side
and all, into the paint can. It was stil gooey and fresh months later.
I do a lot of glue-ups with PL Premium now, and have decided it's
easier to store it in a metal can vs. big-ass tube. The can works
better than the little tube-tip condoms you can get at Lee Valley.
The dessicant is a great idea, to you tape it onto the lid or something?
Actually, I had small quantities, and the whole glue bottle fit inside
dessicator (paint can had a half pint of dessicant like sand on the
Our lab also used big heavy glass dessicators, with vacuum fittings on
and greased-ground-glass flange seals. That was for the expensive
samples; for the glue, I cheaped out and bought paint cans.
If you want something big, a (dead) chest freezer might do, with a few
packs to keep humidity down.
All of these comments are great, and no doubt reflect real-world useage.
The best luck I have had is using propane gas to seal containers. As others
have said, it is heavier than air and won't "leak away". I have even used
it to seal a container of "Liquid Rubber" for over 2 years and the stuff
Not that I'd really recommend it for long term storage - but then again I
have no vices (:) smoking (REALLY - THE ONLY ONE I DON;T DO), swearing*
(damn), drinking (double damn!)
I don't recall if it was Rockler or Woodcraft who carried an accordian
bottle in different sizes. I don't think they were particularly cheap,
Poor seal at the lid/ rim junction. You would have to craft a gasket of
something thicker and with better resilience than waxed paper.
And don't ya just love the crap that forms in those partial cans of $20/gal
latex? You have two quarts left and a bunch of rust dandruff from the metal
rim. It's almost enough for you to change brands just to get the plastic
