Most of my projects are painted white using a roller, whenever possible. Normally I will pour the paint onto the project (like a shelf) and roll it out, hitting the hard spots with a brush. It's a pain to open the can, stir it thoroughly, pour it onto the project, and close up the can when I'm done because of the paint that gets into the rim of the can. I have a lot of crystal clear one gallon milk jugs. Is there a reason that the milk jug would not be suitable for storing latex paint? As the the paint volume gets low in the jug, will there be too much air in the jug? It would be a lot easier to pour a little paint out of a milk jug than it is to handle a paint can. I could even shake the jug to avoid having to stir the paint.
