[Boatanchors] Coils and the winding thereof

[rbethman]

Shellac is actually a VERY good sealer against water/moisture.  It is 
the first thing to apply to a ceiling that has water spots from a leak 
that has been repaired, AND for decades, (MANY), libraries always coated 
the backs of books with shellac when they got new books in.
