The metalworking content is that I bought two old cans of brake fluid for the metal cans. One will be used for Ed's Red - the acetone evaporates through plastic, so for longer term storage you need a metal can. I may modify the cap of the other one to become a dispenser.
Before I discard the old brake fluid, is it useful for anything around the shop? BTW, what's in brake fluid?
