Not just that, also:
1. Some foams leech plasticiser from PVC, making it brittle.
2. It'll make it difficult to remove them in future.

Thanks for the heads up. I will use sheet as close to the wires as I can,
and jam cotton wool down the sides in future if they get damp there. I will
squirt foam around under the standoff bits, and the 2" strip of "andes"
plastering along the top of the box.

Might even make it a usable space for dumping junk.
