This may sound like a lame question, but is it required/recommended that aerosol cans (breakfree, gun scrubber, etc.) and spray bottles (MPRO7) be stored upright, or can I store them horizontally?
I want to put them in something hard and portable like ammo cans for compact storage and easy mobility.
