How to keep well pressure tank from sweating

Question

We are having very hot & humid days. The pressure tank in my garage is sweating profusely. What is the best method/material to insulate it.

The tank sits on a plastic stand and the fitting is on the bottom of the tank.

Thanks for any help.

If the well pressure tank is wrapped with fiberglass insulation, then ifany ambient air gets in there, won't the insulation get wet and mold?  Itwould be very hard to completely seal it because of the plastic base andthe fitting on the bottom.  Of course, it is the botton part that sweats.

I wrapped mine with fibreglass insulatio batts and covered from top with a vinyl garbage bag. Wrapped near the bottom with a nylon tie-wrap and that diminished the problem significantly. Not sure that the sweating part is necessarily the bottom - that's where the moisture falls to from all over the tank. Running a dehumidifier nearby in the hot months will fix the rest of the problem if still present.
