I know much has been written on this topic before but ...................
My front windscreen rubber seal is not original but i don't see any sealant between the roof and the chrome of the screen unlike all other Rover P5s I have seen. I propose to rectify this BUT are there concealed drainage holes at each end on the curve, or can I run the sealant round towards the chrome joint at the sides?

There are no channels and loads of sealant is essential

Yes, try and get it under the stainless trim. Ideally no water at all under the trim. When I did mine I used black silicone bathroom sealent with a 25 year guarantee !
That was over 10 years ago and not a drop has come in since. I also used it around the glass.

Also if you keep your car garaged all the time and avoid heavy water in that area when washing the car you should still be fine unless its totally had it.

Eric there are no drainage holes in the corners I have seen a few caused by rust! If the screen is not packed correctly and the water finds it's way to the bottom of the opening and it cant get out causing rust holes, garaged or not  |

Hi All,
I had the old girl out today an got caught in very heavy shower of rain which left a sizable puddle of water under the handbrake.
There is a pretty obvious windscreen leak on the drivers side, the rubber isn't a tight fit and has perished under the leading edge (it's a damp sludge under there.
Two questions for people more expert on P5Bs than myself.
1. What is the best way to dry out under the rubber seal without either damaging the remaining rubber or windscreen.
2. Assuming I can get it dried out has anyone used the sealant from Wadhams or would you recommend another product?
I want to avoid having to replace the whole rubber if at all possible.
Thanks

If the rubber is perished it would be difficult to seal it up as it would be difficult to lift the rubber to squeeze in the sealent.
The only way to dry it out is to keep it in a dry garage.
When I re-sealed my screen I used black silicone bathroom sealent from a hardware shop with a 25 year guarantee !
After 15 or more years she is still leak free. It is a messy job and you need to get in as much as possible and also seal where the stainless trim meets the roof.
The screens leaked when the cars were new, so quite a challenge to get them dry.

Thanks
The top edge is still reasonably flexible underneath but it has come away from the screen.
Under the leading edge is now a black goo.
I should have enough space to get the sealant under.
Looks like the leak is very localized thankfully so I will clean out what I can and give the sealant a go if I can get a few dry days !

These really are hand fettled cars and fitting and sealing the windscreens (if done properly) is a time consuming job. I use black windscreen mastic with a cartridge gun and seal both edges around the full perimeter of the seal where it contacts the steel body. It can be a very messy task, especially cleaning the excess off with turpentine. It's best to try to free and clean the seal lip with a suitable tool prior to injecting the sealant.
A hand held hair dryer gun is a useful tool for removing/evaporating trapped moisture between the seal and the steel body.

I had a similar problem the first time (in 22 years) I had my P5 in the rain. I bought a cartridge of black RTV sealant from my local auto parts store and filled in all the gaps plus a bead at the windscreen/seal joint and around the chrome surround for both the windscreen and read window. After two years, no leaks yet. I should replace the seal but from what I've read on this forum, it is not a job for the faint of heart so I keep putting it off.

Arbomast from Wadhams has done the trick. It's messy stuff but seems to have worked!

The rain is entering my car too. I thought I cured the problem with lots of sealant, but no. Is it necessary to put sealant between the glass and the rubber too?

Yes but Captain Tolley's Seek & Seal is better than the blackstuff. There may well be rust perforations in the screen channel especially around the bottom corners

Never heard of Captain Tolley's Seek & Seal, but I looked for it on Google. Yep, this might do the trick. Thanks!

If you have scrolled back and seen my previous replies, I can give an update. I have just had a week in Scotland and done just over 2000 miles. I was fairly lucky with the weather, but there was some torrential rain - and not a drop of water came in.
When I re-sealed my screens I used 5 tubes.

I have used more black sealant to fight the incoming water. After that I obtained a bottle of Captain Tolley's Seek & Seal so I applied that too. Around the windscreen it did not sink in, I guess the sealant cured the leaks. Then I tried it on the rubber of the rear window and there it quickly disappeared on two separate locations. So, I put a bit of black sealant in those places too. Fingers crossed during the autumn rainstorms.
