The VP canisters are fabricated so as not to require any special anything as it relates to storage.
You, as the end user, purchase it (whether it be 5gal pails, or 55gal drums) then chuck it into your garage, etc. & no worries.
Been doing that myself now for over 5yrs straight and never an issue.
I am not one to subscribe to the philosophy of mixing. I purchase the 100% Methanol, which is exactly what gets put into, and used into my SHO, as well as for storing.
I too, like BAM_SHO can't speak for, or vouch for, other products.
