Fitting glass with glazing bars - what sealer to use, if any?

[usenet]

What does one put, if anything, around the edge of glass held in with glazing bars, to stop it flapping about and to seal it?

I had some wooden windows made up a couple of years ago and the glass supplier fitted the DG units for free, he used glazing tape which was a neoprene profile, flat one side with self adhesive coating and a ridged profile on the outside. One length on the frame, one length on the bead, fit glass, squish the beads down and nail in. As some of the windows were on the ground floor I later remade the joint to the frame with security glazing tape, which is 2mm or so foam with v sticky adhesive both sides and glues the glass in the frame.

If you don't want the faff of that (it is v quick for a lot of windows) or can't get the tape, I would use the kind of glazing sealant that comes in tubes for caulking guns (screwfix do it) and apply a continuous bead to frame and bead before assembly. I'd prefer it to putty as it remains flexible and will gloop into corners more readily.

Wickes double glazing sealing tape. For some reason B&Q and others don't seem to stock an equivalent.
