Windscreen rubbers

#1 Post by Bunji »

Will be taking out both the front and rear screens of a 72 Toledo to replace the headlining. Presuming it is a good idea to use new rubber seals when replacing.

Looking at the parts catalogue I think I need:

904111 Front rubber seal
613960 Chromed beading
611437 Joining piece (car currently appears to have 2)
808671 Rear rubber seal

Am I missing anything?

Sealant, there is some debate about whether you need it but in my experience the modern repro seals will not seal unless you use a bead of it on the metal lip and inside the seal itself. You need the sort that doesn't set hard, used for classic windscreens.

You can try to fit it dry but I tried that and it leaked in both corners.

I am still having bother with water getting past the screen rubber on the driver's side and dripping down onto the floor. It doesn't help that the design of the screen and frame leaves a large puddle sitting in these corners. But I think the real issue with my car is that it needed a new screen with rubber in 2018 and the glass seems to be marginally too small at the bottom corners. I keep reapplying Arbomast screen sealer and trying to push it between the rubber and the glass but haven't completely cured it yet.

On my race Sprint I lifted the rubber in the corners and applied a bead of black sealant on top of the glass underneath the rubber, additionally, I put another smear of sealant in the corners on top of the glass and smoothed it to the contour of the curve with my finger.

As the car is stripped out, before this was carried out you could see the water dripping from the corner down the bulkhead due to this pooling in the corners.

Since this was done it has never leaked since and that's probably been about 4 years.
Come and see some pretty shoddy, slow driving of a really well prepared competition Sprint here!

My advice is take it out and refit. I tried to fix the issue the same way as you, by forcing the sealer under the rubber, on the glass side and frame side. It doesn't work I am afraid. When I took the screen out, most was just sitting on the surface of the rubber. The only effective way is to apply it is screen out and then run a bead along the frame and another inside the rubber (not sure that is technically necessary but I did it because I don't trust modern rubbers).

The other issue you could be having is rust. it can be surprising well hidden by the paint and I didn't realise quite how bad mine was till I removed the screen and gave the frame a good prod. Rotten in both corners and once that has happened, there will be rot further down, water finds its way into the box section behind the dash. Not especially difficult to weld, if you have the interior out of the way but if I hadn't welded it up, it would never have sealed.

Ive never used any sealant and not had any leaks on the last 5 ive fitted, make sure the screen is clean and the metal is smooth, fit using a professional screen fitting rope and soft mallet starting at centre bottom making sure the screen is centred the trim can be fitted into the rubber before fitting the screen although on the last one i fitted i done the trim after
