Several commercial cavities that I worked on had a very thin "fiber glass +
epoxy" cylinder that
dropped down around the fins, it was a sheet that was glued into a cylinder
with a white cement I
was once told it was done with "dental cement." ??? They were 1/32" thick or
thinner.
G-10 has been known to support combustion, most of the fiber glass + epoxy that
I have found near
high Voltage was made with a white hard glue that looked like white epoxy, but
obviously is different.
