Cheap RTVs such as used in bathroom sealant has a vinegar smell and will attack
copper. In a small confined space inside a radio that's not good. In an open
outdoor environment where the gas can escape it's not such a problem. Dow
Corning and others make RTVs with benign contents, but at a considerable
increase in cost.
Surface mount components have practically no exposed copper and pcb tracks are
not exposed, so, I wonder whether the acetic acid attacks the tin coated
contacts.

Subject: Re: [Elecraft] K3 mobile
OK... May I ask why?
I have seen it done in commercial products and I recently did it when I was
assembling
my SoftRock receivers because of my concerns with the #30 wire breaking.
The two reasons I might think of would be any detuning effect or fear of the
material used
attacking the wire insulation.
Any wisdom on this subject out there? I did not see or am not aware of the
Elecraft
advisory.

There are at least two ferrite core transformers in the K3 that are
supported only by their thin wires. I'm concerned that they may not
survive a mobile environment. It would take only a dab of RTV
(silicone adhesive sealant) to secure them, but I don't know if this
has been discusses or approved.
