All PVC is hygroscopic especially when used at high frequencies.  It's best
to sand interior and exterior, then paint with 3 separate of Glyptal or
other HV insulation.  Interior sanding is rapidly accomplished by using a
sanding "flapper" on a dowel (or other extender) on an electric drill.

Some experimenters would say this is totally not necessary.  I recall a
friend in high school who put over 90,000 miles on his Mustang without ever
changing the oil . . . . . . . . . . . . . . . .but, I can't recommend this
procedure.
