The reason paint goes off after being opened and used is the
large quantity of new air when you replace the lid.

Your better dropping a peace of plastic in the bottom

Or fill the space with some inert gas?

Store the tins upside down.

Makes no difference once the tin is opened and new air introduced.


With oil based paints, it ensures that the skin is under the paint,
not on top, when you come to use it.

The reason for rotating tins was to help keep the oils and pigments
mixed, otherwise they eventually seperate

Now that is a load, that will not keep the contents mixed.
It WILL help keep the paint from stratifying because the heavy parts
always sink to the bottom. Constantly changing where the "bottom" is
HELPS keep the paint from becoming a cake of pigment etc covered by
oil.
