Painting the inside and out with rust preventive paint greatly increases their life after the holes have been drilled or punched in,... and with a little extra wire for handles are added, (hardware cloth, Chicken wire or such make great wraps) they can last for years and be fun. With a liner of glass or plastic they are great for floral arrangements. Tin cans to treasure!
