[Elecraft] hot glue K2 toroids?

[Matt Palmer]

I doubt you use actual RTV but a RTV-like sealant. RTV contains acetic
acid and will eat/corrode electronics and is a no-no for mil hardware.
In mil spec hardware I doubt you are winding your own toroids. While
it was common practice to do your own air wound coil knifing, the CMMI
people have pretty much axed that practice as it makes it too easy to
loose the recipe and manufacturing costs are too high. Now everything
is bought with a ridiculous tolerance spec from coilcraft or its laser
trimmed. (just gave the manufacturing cost to someone else really, but
the big wigs never realize that)

Just wanted to give my 0.02 before some people got the idea to goto
the hardware store and grab RTV, make sure you know what they are
using as the solvent!
