Yes, Barge will get you high, or blow up your shop if you light a ciggie ... good ole high-VOC stuff. And Ian - there are many kinds of contact cement. Most of them are intended to be firm. You wouldn't want to glue down Formica and have it wiggly or peel up, would you? Shoe glue, on the other hand, is intended to remain flexible. The problem with high VOC liquid in certain cases, esp in hot weather, is that it will attack vinyl and potentially melt it. I don't know if any camera mfg is such a skinflint
as to use thin vinyl on actual camera bellows. I would outgas and eventually go brittle itself. I have seen vinyl used for aftermarket compendium lens shades.
