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
