Philip,

Copydex would have similar problems to any latex concoction - it is a 
little too thick to allow the bellows to fully compress if you have a lot 
of pinholes to cover. In addition you may find it difficult to mix any 
opaque compound in with Copydex before it starts to set.

You can mix acrylic paint with PVA glue if you must use glue. I prefer to 
use acrylic paint on its own having tried both methods. Two coats (or dabs) 
do the trick and remain flexible.

Cheers,
