leaking windscreen rubber.

[samuria]

my screen leaks in both corners it is a new rubber. whats a good cure has anyone used captain tolleys creeping crack cure????

[moggiethouable]

I used (no giggling please) clear bathroom sealant on the outside of the screen, between the rubber and the glass.
Remember it could be leaking higher up and running down the seal if the water is in the lower corners.
So far so good

ARR, Jim lad! I've used it and it improved matters noticeably, no idea what had been done to the screen before but I'm hoping another application will do the trick.

Ive just watched the video and it seems pretty impressive stuff.
If my leak comes back I may well invest in a dab.

Sounds like a plan as my car has the same problem, a leak at the bottom of the screen (which has had mastic applied which reduced it somewhat, but didn't fix it)

My standard practice is now windscreen sealant / mastic initially, followed by CTCCC. Be sure to apply CT along the top edge and down the side as well as along the bottom. It may need a few applications, but it WILL work (assuming that it's not a rust problem with the frame!).

I have the same problem, rarely take the car out in the wet but after last weekend need to get things sorted. New rubbers (10 years ago) with no sealant when fitted. I also need to sort out my hood as not only had wet feet but when driving over 40 MPH a spray of fine water was hitting me in the face, comming in through the gap between the hood frame and top of windscreen. Taking a good coat with hood and wellies next time.

Clear fish tank sealant works everytime it holds the pressure of a full fish tank and never had leaks on my screen again and cheap

[chickenjohn]

Be aware that some of these sealant contain solvents and chemicals that could attack the paintwork of your car. Could stop the leak only to have a screen surround rust problem!

The best cure for a leaky windscreen rubber is a new rubber! My convertible had a new screen rubber three years ago and it does not leak a drop!

The main cause of screen leaks seem to be when the rubber is not 'pushed' into the corners well, the filler strip is supposed to do this but I've found with the endless screen rubbers they could do with being made slightly longer before being glued together, as the filler strip sometimes has a job stretching the rubber fully into the corners.

[JOWETTJAVELIN]

I believe all the screen rubbers were originally fitted 'dry sealed' - i.e. no sealant/mastic used. A drop of sealant won't go amiss but just be careful about trapping rust and making future corrosion problems - it's best to test with a hosepipe where the leak is actually coming from before bunging up every nook and cranny.

As a sidenote - the splitscreen seems to have included leaks in the factory specification.

It's interesting. I recently fitted new rubber to the front of my split screen (prob worst job on a Morrie I've ever had to do). Even with brand new rubber and sealant I still get dribbles at each corner. Yet this can't have been normal in the 50's - there's a great film of them testing the water tightness at the factory with a full tank of water with fish swimming around in it attached t the front screen! I like the fish tank sealant idea - might be worth a try

[JOWETTJAVELIN]

If the vast majority of splitscreens leak this would suggest it was and still is a design fault.

I reckon that because they could easily have sold every car they made, little faults like this would have passed quality control, and just got worse over the years.

The thing to do is pinpoint the leak then take remedial action.

Confirmed that Capt Tolley's does work after being out in the rain yesterday.

Needs to be applied carefully as it runs everywhere being so thin, but it does the job
