Decorating with metal buckets is easy and inexpensive, even when you customize your paint job. Some people leave the pails plain and unpainted, but painting metal buckets brings color and vibrancy to your garden, table top or front stoop. Use colors to match or complement your current color scheme or decorate the bucket with creative designs and themes. Whether you use the bucket as a flower pot, candy dish or water collector, a custom paint job adds to a metal bucket's simple charm.
