I'll just give an alternate view - but point out that Pliobond will work just fine.
Pliobond is a high strength permanent contact cement. For leatherette on cameras, a general purpose contact cement (like Lepages) will work just as well. I will point out that "permanant" may not be what you want on a camera, as the original leatherette is designed to be removable during servicing.
Most factory leatherette is attached with a double-sided tape adhesive, which is applied to the leatherette before cutting. Most camera leatherette from 60's can be heated and peeled off, and the old adhesive layer removed from the leatherette. Double sided adhesive tape (ie:3M) of various permanence can be easily re-applied.
All that said, I have used household contact cement successfully, and it is relatively easy to remove later.
(Note that modern cameras - film and digital - often have a rubber cladding, which may not bond with contact cements)
