I have a couple of Speed Graphics with FP shutters that work great, but the fabrics are a bit thin and show a few light leaks...not holes...just a thinning of the material. Is there a recommended method of sealing this without compromising the shutter performance? Thanks. Fred.

Bostick and Sullivan sell a flexible latex material that might work. I'd brush it on thin and do small sections at a time letting it dry. I've also heard black acrylic artist's paint works

Thanks, LEs. (You signed with capital LE and small s, so I assume that's your new signature, since you rarely err.) I'll give it a try. Fred.

I have used "Plasti Dip" >spray< with success on the cloth shutters! Hang the shutter on the cloths line, bright sun will illuminate the pinholes!
Even with a light spray the cloth can become to thick to roll up correctly, so I make a puddle of paint on a stick and dab the paint on the pinholes with a brush! Caution, let it dry for about 24 hours before rolling the curtain up, it has a tendancy to glue itself together, if you dont! Works great on bellows also...but remember....the 24 hours dry time!
Have a nice day..........Bert
