Apparently, maybe it would help a little more to store the metal containers and whatever containers upside down or the liquid around the lid or opening like wine bottles with the wine around the cork. Gas, fumes, and evaporation is much "thinner" than the liquid inside and has less possibility to permeate out through the smallest of path. Kind of an extra sealant.



yes it can. especially one that has been opened and re-sealed. solvent fumes are extremely thin, much smaller than the product it is thinning out. and can escape thru microscopic cracks in the cans and containers that liquid can get thru.
do a test yourself. get access to a GOOD accurate digital scale. take a unopened paint can. weigh it. and record the weight to the 100th of a gram. open it, then reseal it. set it out in the sun for a 3 or 4 months. i guarantee it will weigh less.
heck even rattle can spray bombs loose pressure even though they have never been used. who hasn't picked up a can that worked perfectly fine 6 months ago that doesn't work now? or better yet a new never used one that doesn't spray 2 years after you bought it. why did that happen because it was supposed to be self sealing after releasing the trigger. and yet there isn't any pressure in the can anymore. where did this pressure go?

and YES storing solvent based products upside down will extensively reduce solvent escape. it still won't eliminate it though.


However, one potential flaw IMO with the can in the sun test, the heated solvent builds considerable pressure that a typical paint can is not intended to contain, the pressure distorts the lid, which might be the main cause of the loss of solvents./weight.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
