I have removed the glass from my 2 part series 3 windscreen:
1) to make it easier to clean up the frame
2) there was evidence that someone had tried to fix some leaks, by the presence of some extra sealant slapped around the edges.
So I thought it would be good to remove the glass, clean everything up and then use some nice new seals.

I can see various seals on suppliers websites for the thick seals that go around the outside of the frame, but initially i need the seal that goes on the glass edge (i.e. inside the frame). Whilst i could just use silicone sealant, i think the best approach is to get a rubber seal that goes on the glass, and then maybe use a little bit of sealant around this to guarantee a watertight seal.

I can see some of these rubber seals for defenders on websites, but i can't see anything listed for series.
Any advice?

You could get some self adhesive closed cell foam tape. Available in a wide variety of widths and thicknesses, you want a pretty small one for that, maybe 6mm wide and 1mm thick. You can easily cut it with scissors, and it is quite cheap, so if you make mistakes, you can just make another seal.

I get it off RS Components website, but there are plenty of other online and physical suppliers.
 
It's not structural like on modern cars where the glass maintains stiffness.
That said i think i would be investigating liquid products that don't break down/degrade over time. Foam strips might do that?

Foam tape does break down over time, due to light. But the metal frames protect the tape to some extent.
The small stuff I use on my portholes lasts about 5 years.
The big tape I use on the weed hatch seems to last indefinitely, because it is always in the dark.
The stuff is so cheap, changing it occasionally isn't really a problem.
 
It needs to be a decent thickness, if not the weld seams in the corners can and will contact the screen causing it to crack, this I know first hand, was a heated one as well!
I used Dum Dum, but think it is NLA.

I am thinking of using a dum dum like tape between the glass and the frame and butyl tape between glass and trim.

Might pay to do a dry run first to make sure the little self tappers will still start/line up.
 
You don’t need anything sticky on the inside between the glass and trim.
The original part used - a thin rubber filler strip - is still available. Part number: 78159.
pa blanchards have it.
