in this or the antique radio group about coil dope. As a
result I tried making some. ...What I did was to dissolve polyfoam shippi=

Proportions, please?
When I was a kid, we just added styrofoam to toluene until we got about the
right viscosity. I have coils that I varnished with that stuff thirty years
ago which are still just fine.
