As you probably know I am a big fan of Gamma Seals. I am talking about those screw-on lids w/ gaskets that turn a 5 gallon bucket into a watertight sealed container. CHEAP storage alternative to ammo cans!
I wanted to post that Home Depot now carries them in their stores, so if you only need 1 or 2 you don't have to mail order them. Not as cheap as mail order but awful convenient! I've found them really cheap online if you do some digging and don't mind buying in 6-packs. The freckleface.com site has been the cheapest for me so far.
Of interest - I read that the chemicals used to make the black buckets are NOT food-grade, so keep that in mind. The other colors all appear to be food-grade; it is only the black buckets that are not listed as food-grade.
I recently found that these lids work for any buckets with the same size lid, which range in size from 3.5 gallons to 6 gallons. I have PLENTY of 5 gallon buckets. I would be curious to know where I can salvage 3.5 gallon buckets and still have them food-grade?
