3. Slide the wet paint lid into a plastic zip-closure bag or the plastic pouches left over from making a trash-bag apron. Sliding the lid into plastic prevents the paint from drying, stops the lid from dripping paint, and provides a clean lifting tab to be able to open, pour, and close the can as needed.
4. Punch holes in the groove inside of the rim, called the lid well, with a hammer and nail or with the sharp point of the 5-in-1 tool and a mallet. The holes allow excess paint to drain back into the can. This technique will also ensure that after the project is finished, the lid can set and seal properly into the can for storage.
