Regarding keeping paint on hand for touch ups; I dip a sponge brush generously into each can of paint at conclusion of any job, then place it into a labeled ziplock bag, then into my freezer. When I see a touch up spot, I pull the bag out, set it on the counter for a bit, do the touch up, then toss it back into the bag and freezer. So easy, no mess, and no procrastination urge needing to be fought off. The paint stays fresh for years.
