Is that so? Plastic would be easier

Thanks all,

That's settled.

I thought foil would be a good possibility, because a) I can buy it readily
in the supermarket, b) it's vapour proof and durable, c) I can probably
lightly stick it with either PVA or some spray on evo-stick I happen to
have a can of. Sticking it, even very lightly would ensure it stays put as
I install the board.

Just glad I don't have to waste it
