It works. But, it makes me just a little nervous when I plug on the socket. It tends to flex which must put a little stress on the leads.
If you use a one part RTV try to find one that doesn't make acetic acid during the cure.

RTV3145 does all of that - it cures fairly firm - softer than hard rubber, but firmer than your typical silicone sealant. And the US Gov't spec for all silicone products restricts the % of acetic acid (actually
acetyls). The stuff is pretty stable in the tube if unopened - the reason I mention that is someone on fleabay has some (recently) expired tubes. Shelf life for the stuff is two years, so it get's surplused pretty often. New tube of the RTV3145 goes for 23-28 bucks, so "cry once" as they say. The stuff is available online everywhere. Use masking tape for potting the stuff. You can't speed cure any RTV (room temperature vulcanizing) Silicone. Skins in about an hour or so, and you can handle it in 24hrs. Cleanup of any extra is easy - I use an Xacto knife - we used surgical scalpels in the Navy - but a razor blade works as well.
