Rust under screen trim

[jamesh]

I wonder if this is anything to urgently worry about.

I've purchased a 1973 P5B coupe, according to the history file it has had both front and rear screens removed and new rubbers fitted in 2011. The rubber appears to be in good condition although there are patches of rust / rust staining.

I don't particularly want to be leaving something that will cause terminal rot, on the other hand if it is something that can safely be left to "watch and wait"

Unfortunately rust doesn't sleep, especially under a rubber molding. If you want to stop the decay you need to take remedial action.

Agreed. What you can see is only the edge. Get it fixed asap.

Sorry to say the seals aren't fitted correctly James and I hope the metal under them is sound? If it were me I would remove the seal and check rust is never just on the edge! what you are seeing is the clips that should be holding the trim so if shortcuts were made fitting the trim?

Thanks for the replies. It is a shame, but I realise it does need doing. I've got a local (ish) bodyshop who will have a look at it for me soon, they have got a few classics under their belt, so it's not something that will be a complete surprise to them.

I'll keep you all posted.

Sadly, when I removed my screen front and back, the metal beneath was like lace!  I had to remake part of  the rear window frame.😬
Don’t wish to frighten you!!

Just for the record, this is pretty normal for P5's, so don't get downhearted about it. The car looks great! There will always be things that need doing, a list of minor and sometimes more major things to do with an old car, but that's the joy of the hobby.

Thanks. I was expecting a fair bit of rust and general bodywork naughtiness in a car that's almost half a century old. I was a bit concerned because of the location. Panels and cills are not as much of a problem as the corrosion is a little more visible.

I'm heartened that the glass was removed ten years ago and no mention was made of any corrosion at the time. Since then the car has had very little use and has been in almost continuous dry storage.

Being well on with my 'bare metal' renovation I recently refitted the front screen. During bodywork phase serious work was required to all four bottom corners of the two screens to rebuild them. With an engineering hat on I am surprised at the very poor design, which allows any water that gets under the seal to 'puddle' in the corners as unable to escape. Further to that, refitting the screen was a revelation in poor fitting, requiring masses of mastic all round to attempt to seal the grass in. There is between 8 and 10 mm of 'slop' to the taken up by mastic so is almost guaranteed to leak at some point. Why on earth this was not rectified early on in production heavens knows. The fix is either for the screen to be made slightly larger or, an easier option which still allows for movement of the body flexing in relation to the glass, would be to manufacture the seals to be deeper under the glass to take up most of the 'slop'.

Of course, there is also the option of which seal you use.  It seems that Scott windscreen seals are often quoted as being the best to fit.  Mine are all on standby, longing for the day when they can be reunited with my Rover!😂

Another chap and i have compared the dimensions of the two seals available and there is only a mm here and there between them and the vital dimension, that between the chanel for the glass and the body, is pretty much the same.
