===========================================>
Sorry,
I didn't mean to imply that using fiberglass might be a methodology for
hermetic sealing of anything, just a means for water entry and corrosion
resistance.
I used the wrapping of the 40-2CD traps as a "possible" application
example, since these guys are just coils, as I recall, not "traps" as we
find on multiband beams where one has coils contained within a cavity or
can.
If you fiberglass seal a container, or seal with some other means of
encapsulation, you will create a water maker environment.
1. just like a sheet of plastic on hot desert sand at night, or
2. just as those end plugs on drooping elements do;
create a long enclosed container for temperature and humidity
modulation with
resultant water being formed in the elements.
Weep holes have a very real reason for existing on the underside of trap
cans.
73,
