Aluminum Foil – A Painter’s Best Friend
Whether you are a professional artist or an amateur painter, some problem will remain common. The worst is losing the cap of a paint box which results in oxidation of the paint and makes it less than desirable.
Aluminum foil is convenient for creating caps. Fold a piece of foil and place it on the jar. The foil will prevent air contact, and the CO2 will eliminate oxidation.
The Aluminum foil is also ideal for crafting a temporary paint palette.
