Greetings,

I had read that PVC should be coated with polyurethane, or the like, because
the surface of PVC attracts moisture.  If you are using PVC, I would suggest
lightly sanding the surface with a fine mesh sand paper and coating it with
polyurathane.

Hello all,

Some coil plans I have say that when using PVC as a coil form, it should
be coated with polyurethane (or similar) BEFORE winding the wire on to
reduce losses. Is this really necessary? I would have thought it just
adds more loss by making the form wall thicker.
