Blackening Agent for photo etched parts + brass
Burnishing Agent for Photo etch Parts and Brass Barrels has been designed to get your brass pieces just look right instantly.
It blackens your turned brass barrels and photo etch within about 3-5 minutes.
If you soldered your PEs, the Agent will blacken the tin solder as well. Please be advised that this only can be true for the most common solder tins.
