Check the condition of the container roofs, I've seen them rust out

Indeed. When I finally get my 24' seatrain home in a week or so..Im
going to have to retar` or coat or so something with the roof. The
majority of it is aluminum..but the roof is steel and has rusted in
places and it did leak last winter.

My intent was to take the sun load off the top of the containers. *There

I was wondering if I put a recirculating water pump to flow water over the

much. *I'm probably going to have to just try it. *I get ag water, so
there's no problem about added cost.

Anyone ever done this?

You guys might take a look at the spray-on bedliner stuff for a tough
weatherproof sealer.

Snowhite Roof covering. Much preferred where insolation is high
(meaning that there is a lot of sunshine).

As for cooling the sides and top - "double wall". I think it was
Buckminster Fuller who designed a double walled, all metal portable
hut back inthe forties. (I think for the War Department.) While the
outside wall got very hot, the air gap allowed for a flow "up" and out
the top, which kept the inside cooler. Neat idea, but the Army went
with the Quonset hut, instead.

One other idea for cooling, keeping air flow going, is to paint
the roof white, then add a stove pipe painted black. That way a) the
roof stays "cool" but the stove pipe will cause a draft as hot air
flows up and out, drawing fresh(er) air in. Steward Brand, Editor of
The Whole Earth News, did that with his container turned office - no
need for A/C or power consumption.
