[Milsurplus] BC-348 cap rebuild advice - thanks

[Sean Barton]

What I call an acid brush is a cheap looking brush made from a piece of 
sheet metal rolled into a tubular handle with bristles crimped in one end. 
They might also be called solvent brushes, flux brushes, etc.  Craft stores 
have them as glue brushes.
