Hello All...
I have a 3 lb canister of Hercules Red Dot that's nearly full. Smells fine and looks OK. I also have a fair amount of Unique that also looks and smells fine. This powder belonged to my father and is probably 30 years old, but has been well-stored. Any reason to Suspect it may be bad? Also, are these powders still in common use?
Thanks!
