Q. Hi There My original question was about soldering copper wire to model railway tracks. Your suggestion of "Dipping Flux", would it be okay to dip a small paintbrush into the flux to apply flux to the work piece?? Kevin
A. Hi Kevin, thank you for your question. The dipping flux would be used before tinning the wire. if you prefer you can use 85-6648 for the same application you have mentioned but the dipping flux can be used with a small paintbrush to protect the solder joints.
