I got a great buy on W296 in 3lb containers. The bottom of the cans are a little rusty. Suppose thats why the great deal.Any suggestions on new containers? Do they need to be dark to keep light out?

The best containers 2 store powder in R FREE. I know somewhere In your home town U have a pharmacy. Sweet talk the pharmist into keeping all the EMPTY PILL BOTTLES 4U.
I have been storing all my IMR and all other Powder that comes in METAL cans in those type of containers,some 4 over 20 years, and they still smell FRESH'''''''''''''''''''

Sometimes the best things in life R FREE

I never toss out a powder can...that way I always have plenty for storage of bulk powder...A wrap of 3" paper tape and a marks a lot takes care of the identity...Surly someone you know has a supply of powder cans.
