the last time i used my own advice to repair bellows i used a few drops of india ink
in some good old ova glue ended up clotting up the glue and making
it kind of useless so i am trying the plasti-dip solution to see if
it works any better.

i have read here and other places on this world wide web
that you spray it on and smooth it with a brush, but the
bellows is still on the camera, so i dont' really want to do that ..
( i have a healthy amount of experience using a spray can and knowing
what happens when *I* use it )
anyone use the same plastic-dip in a can ?
i've looked in my home goods stores and they only have spray cans ...
any national hardware chain carry it in small ( NOT 1 gallon ) cans ?
while i'd love to put plasticized rubbery hand grips on EVERYTHING I OWN i think it will get
old when i put a rubbery coating on my hands/arms ( like the first surgical gloves )
or my feet so i don't have to wear shoes ... it'll end up like when i was shipped 10 cubic yards
of gravel instead of 3 ( or his yard-scoop was enormous ) there is only so much you can do to be "creative" and use stuff up.

if i can't get small cans, any other products that will seal bellows, i don't mind buying 4oz containers. even a few .

thanks for your bellows patching material expert help

I buy a pint at Tru Value hardware store and use a little brush to seal pinholes in bellows. Not sure of the name brand brand but it was around $8 if I remember

I have found liquid electrical tape to be the best solution. Small can comes with its own brush and dries well without residual stickiness.

The product is Plasti Dip. I get it from my local Ace Hardware store (http://www.acehardware.com/product/index.jsp?productId=3573713). Also available online.

It does work by just painting it over the pinhole, on the inside of the bellows. Use an opaque color. Lay it on thin. Let dry. Test, repeat if necessary.

I majored in Plastic Dip usage in 1986. 20 gallons, $100 and then had fun.

Scroll to the bottom under, "The History of Dragons 1986-' to see what it can do, I still have 3 Babies right here.

Another thought if you can only find cans is to spray into a Dixie cup or similar and then use a brush and dip it in the cup?

John, good idea! You won't have to wear gloves anymore for developing :)
I've only tried the liquid electrical tape and brushed it on. ( great for small pinholes, by the way, and stays flexible after it dries... but let it dry somewhere you don't need to breath! )

I see this stuff on late night TV all the time. The guy coats a window screen boat.

20 Gallons?? Geez! were you drinking that stuff? I used to use the brush or dip stuff, but I do like that spray-on. It is much easier and I don't make such a mess.

The window screen sculptures are big and I was pouring it on.

My preference is black acrylic paint. it dries w/o tackiness and stays flexible. I paint a thin layer inside and out with the bellows stretched and let it dry that way.

+1 for the acrylic paint. The acrylic paint for fabric stays flexible.

Harbor Freight Tools has it in cans in some stores.

The liquid electrical tape brushes on and is very flexible. It seems to me to be the same material as the dip. I would use it on the outside only it is very shiny when dried.

If you want to try Walmartish snake oil products, hope you've got a spare bellows to test first. Some of these things can outgas and potentially mess with the film, stick to themselves, who knows what. You'd be your own guinea pig. Ordinary black silicone RTV sealant would be better, but with one distinct limitation - once you start with silicone, nothing else will stick but silicone! An industrial supplier like McMaster Carr would have a better choice of these things than a hardware store,
including brushable hi-tech varieties. At least its inert and very temperature resistant once cured. "Liquid electrical tape" would work fine too, at least on the outside. Plasti-dip is also vinyl, so should be on the outside of the bellows only, since vinyl keeps slowly outgassing and could smudge up your groundglass just like
what vinyl dashboards do to the insides of car windshields.
