I found that I could not live without the glue brush can.
I bought one of these about 3 years ago. While I had problems with the first one, Weaver Leather's excellent customer service took care of me beautifully.
I do not use this on my smaller projects but when you have something big like a belt lining or notebook cover lining, this glue brush can is the only way to go if you want to get it done quickly without a ton of mess and glue stringers getting onto your project and workspace.
My applicator finally bit the dust after several years (The pumping mechanism stopped working) and I was not planning on getting another one because of the cost...not only for the glue brush can itself, but for the additional brushes as well.
Once I tried gluing from the bottle on a belt lining, I knew I had to get another glue brush can.
In order to maintain my brushes, I soak a paper towel in acetone and then wipe off the glue from the brush. If you do not use the glue brush can for awhile and the glue clogs the brush, I was surprised to find that I can remove (unscrew) the brush and submerge it in a small jar filled with acetone for a couple of days. I was surprised because the acetone doesn't destroy the brush fibers and to can then "pick" the (now softened) glue out of the brush cavity.
