I have a Badger 360 that I use exclusively as a gravity feed. Acrylics are the only paints used in the brush. On Sunday, I was spraying Gerald Voigt's Talon Aluminum. The brush leaked like a sieve through the hole beneath the cup forward of the rotary seal . . . at least that is where it appears to come from.
The brush receives a thorough cleaning after every color. There shouldn't be any wayward dried paint. As much as I like the Talon aluminum, I'd prefer to put more of it on the model than on the floor.
Anybody have any ideas what may be occuring? Thanks!
