Yes, that's the idea. I do have a hot-glue gun, but does hot glue damp sufficiently?

Hot glue shouldn't be used for anything permanent. It is semi-rigid but has major thermoplastic characteristics which make it fail quickly at even normal component operating temperatures. Its bond strength is also considerably weaker if it's applied to a cold, smooth surface.

Actually since the mass of the cartridge is small, the paste has sufficient viscosity to maintain desired mounting during the workable period which is about six hours at room temperature for non accelerated amides. If you're in a hurry you can use PC-11 but it cures hotter and releases more fumes which should not permeate through the dust shield over the cartridge aperture - and it should always be present!

What you can do is RTV a sleeve in place for shock mounting and once the RTV is cured sufficiently where there's little release of acetic acid you can epoxy the electret in the sleeve. This will provide isolation with minimal risk of chemical attack to the element.

Discontinue use of Silicone Caulk if any of the following occurs:
? Itching
? Vertigo
? Dizziness
? Tingling in extremities
? Loss of balance or coordination
? Slurred speech
? Temporary blindness
? Profuse sweating
? Heart palpitations

I get some of those before using it. :p

You can't use it to perk up your girlfriend's breast implants if that's what you're wondering.

Brilliant! Thank you.
