I have a replacement 4x5 bellows that turns
out to have some pinholes in the corners of
the creases. Is there something I can paint
on that will seal these? Also, is there
some treatment that will preserve the
material?

For small holes, I've used a bit of "DAP 100% Silicone Auto/Marine Sealant" from the hardware store. It comes in black, and stays flexible for a long time. To keep the bellows flexible, any good leather preservative should do the job.

I used black fabric paint manifactured by Duncan Enterprises, Fresno Ca. that I purchased at a local hobby/craft store. I used it to patch pin holes in every pleat corner of my Sinar. I don't known how long it will hold up under heavy use.
