Ordinary house paint in cans, not aerosol, can be stored that way also. 1 litre/1 quart, 4 litres/ 1 gallon are examples. it helps to stop skimming and any rust at the lid. if left too long it will skim midway which can be cut out using an old sharp filleting knife or similar : after opening simply slice all the way around the inside of can and remove the disc then start normal stirring for use. I've also had luck with polyurathane finishes and trailer / steel finishing paints using this method.
