I scored numerous 5 gallon, 3 gallon and 2 gallon plastic buckets from the Wal-Mart bakery. They also provided me with the corresponding lids. The 5 gallon and 2 gallon lids have the rubber gasket and appear to be re-sealable. The question is: Should I attempt to reuse these lids (after a thorough cleaning) or just buy new lids? Any responses welcome.
