Here’s yet another trick for minimizing the evaporation of paint or varnish that’s kept in a store-bought can. With the lid firmly secured, turn the can upside-down for just a second or two, then return it to the right side-up position. Turning it upside-down coats the entire inside top surface of the can with a thin film, helping to seal the lid.
