Little late, but saw your other post about the tank and storing it. Here is how I always stored my tanks in FL in a storage shed (not temp controlled) when I would reply.
Silicone lubricant and apply it to all of the seams (inside and out)
Put tank on a pallet/box I made from some 2x4s and some super thin plywood, put stand on a pallet I made from some 2x4s, wrap tank with shrink wrap (Saran Wrap works fine if you cannot get shrink wrap),, put shin plywood over frame built around tank, and then place tank and stand where ever. I never stored my tank on the stand, no matter the size. Just in case.
Never had an issue with silicone drying out, and this was when storing it just south of McDill AFB in that barren death hole of heat for 15-18 months at a time lol.
