Is this normal? D1 windscreen seal

[MSkinner]

Just when I thought I'd nailed down all the leaks in my Disco, I hopped in it this morning to find a dripping headliner from above the windscreen to the rear cargo area. It hasn't rained here like it did last night since I've had the Disco which is probably why I haven't seen it before.

Anyway, in trying to find a solution to this new problem, I noticed my top windscreen seal looked a little odd, to me anyway.

Are the below shots how a D1 windscreen seal should be?

That's how my old Disco's screen was (1998 Disco). The windscreens are bonded in and when they are replaced they need new rubbers/seals/mouldings (or whatever they are called). I had mine removed and re-sealed, but it always leaked. It was around $230 from memory - I didn't have to get a new screen and they were lucky to remove it without cracking it.

My car started to get rust in that area as water obviously sits there for ages under the rubber. I always thought it was a strange way to do it.

PS. If you feel the need to fill it with some sealer, don't use what I used. It was called windscreen sealant or something like that (I think made by Septone from memory). It seemed to run this dirty film of crap down the windscreen over the years and it always annoyed me and I had to keep cleaning it off. I think next time I would try and fill that whole area under the moulding with some really good quality silastic. I've heard some Sikalfex products are excellent. I'm not an expert, these are just my thoughts.

It did slow the leaking down though...so probably a better silastic would completely stop it!

What happens when water gets in under that 'lip'? Its not like its water tight at all. On a warm day, you don't actually need a screwdriver to pry it up. You can lift it up with your finger.

I had a new windscreen fitted once, stone chip.

leaked after fitting, got the shop back in to fix it.

They said a bit was missed, never leaked after the fix.

im with MSKINNER, the septone stuff is crap, ideally, fill the gap with sikaflex, its the same eurethane stuff they fit windscreens with

My understanding is that the bond is under that lip and behind the windscreen and that lip is just cosmetic. So what I did was lift that flap up and squeezed the goop in there until it came out. (I masked it with tape first). I then gentyl pressed the lip to squeeze out just a little more, then wiped it and you could not tell that I had ever put any goop in behind it. Couldn't see it at all. Except now there was no spot for water to sit in behind that lip.

As and aside, to test where the leak comes from, the trick is to spray a mild soap detergent/water mix on the outside and with an air compressor blow air from the inside out. The soapy water will bubble where the leak is. But a bit hard with no air compressor.

I had the same problem on my ' 96 Disco 1.
I got some windscreen sealant, then starting from the middle of the windscreen, I applied a really good bead of sealant right down below that rubber strip in your photo, running it towards the drivers side door, problem fixed.
This remedy is as recommended by Land Rover service bulletin, as the leak is/was a known problem.
Hope this helps.

I used the windscreen sealant made by Septone and it was horrible. For a couple of years it seemed to seep and leave this filthly film of crap on my windscreen. (Had to use acetone or metho to wipe it off every few months). So my recommendation would be to use another brand.

As for not being able to use silicone on metal - I've never heard that. Is that possibly only the acid cure variety? There are definitely silicone's available to use on metal - look at:
Selleys Roof & Gutter Silicone (http://www.selleys.com.au/Selleys-Roof-Gutter-Silicone/default.aspx)

I'm not recommending to use it for a windscreen - I'm just curious about not being able to use silicone on metals.

Anyone got any more info on this?

yea, the problem is that most silicones use acetic acid as part of thier recipie, so you need to use a non acid cure silicone.....


but that said, DO NOT USE SILICONE, if you EVER need to get any part of your vehicle resprayed, your panelbeater WILL kill you

use sikaflex polyurethane adhesive/sealant, its what windscreen fitters use, just dont ask me which particular brew of sikaflex they use
