Paint always seems to build up in the lid groove on the can during every painting job. This often causes paint to run down the side of the can. You can eliminate this problem by punching several holes in the lid groove with a 4 or 6 penny nail . These holes permit the paint to drain back into the can each time it accumulates in the lid groove. These holes in no way affect the resealing of the can, since the lid seals by pressure on the sides of the groove rather than on the bottom.
