I know some questions akin to this have been asked in the past, but I can't seem to locate anything on reconditioning synthetic bellows. Specifically, I'm tryi ng to squeeze about 6 more months out of the bellows on my Deardorff 8x10, as a new set of bellows does not currently fit into my budget. The bellows themselve s appear to be made out of about the same material as military raincoats. Is it possible to do anything to these bellows (or other synthetic bellows, for that matter) to make them any more flexible, or am I basically stuck as is until I ca n afford a new set? Thanks.
