Dammit. "Veneered" I meant, of course. Apologies.

I stored some outside 4 years ago horizontal and on a stout wooden frame
approx 18 inches off the ground (soil) then just covered with a couple
of sheets of plastic and waxy groundsheet, tented it slightly and it was
ok 3 years later.
I have since put up a plastic corrigated shelter (roof and 3 sides) and
moved it there a year ago. As far as I can see it is still all ok.
