Hi, well i usually use acetone to remove dirt and the printing what ever
color. I dont usually do anything to the inside and a light sand first and
then a coat of polyurethane is not a bad idea. it prepares the winding
surface. dirt can be your enemy if its under the wire. carefull prep and
coating makes a coil that will last a long time. cul brian f.
