Steve,

RTV is a silcon sealant - like the stuff you put round the edge of your bath to
stop it leaking. RTV is Dow Corning's trade name for it's family of sealants.
If you really want to use this to stop the device leaving the board, make sure
you get hold of a grade that doesn't liberate acetic acid on cure. Normally
it'll tell you on the side of the tube and if it does it'll smell of vinegar.

You can probably tell that I wouldn't rate this as a solution to your problem -
but good luck anyway!
