2 x bottles of Tulip "Slick" dimensional fabric paint, black. I have a wacko experiment to perform on my Whole Plate camera with bellows that are perforated on every pleat and corner.
I am going to coat the entire bellows with several layers of this supposedly flexible black fabric paint and see if it will cure the light leaks and be durable.
Not real optimistic, but a $10 gamble might allow me several months of use prior to ordering a new bellow.
First coat is on and it's surprisingly flexible and only slightly tacky. Covered most of the tiny holes, but some corner holes are still there and will undoubtedly take a few more coats to seal.
The real test will be folding the camera up and seeing if it even will unfold after being stored!
No guts, no glory...
