rear window solution

[cellardoor]

I have noticed water seepage in the parcel shelf of my 1983 500SEC. The rear window seal has been alowing water in.
I have fixed this problem like this.
1. Remove the siler metal trim from the rubber, being careful not to bend it.
2. Lifting the inside lip of the rubber where it meets the glass and getting the mud and water out with a cloth, making sure that I got it dry inside. The seal is so slack I could get the cloth right round the edge of the glass.
3. I chose black silicone sealant in a cartridge with a skeleton gun so i could press the end right in as I applied it. I ran in a good size bead of sealant around the sides and the bottom of the glass.
4. As i moved on the rubber lip naturally folded back sqeezing some of the sealant out. When i had finished I lightly ran my finger along the rubber alowing it to re-seat itself.
5. I took a pointy bit of wood from a nearby skip and ran it around pushing the sealant leaving a clear line about 1mm between sealant excess and rubber
6. The next day I skimmed the excess off with a razorblade.
Job done. I think this will be a great seal. It cost me £7.50
I would say this will only work if you catch it early

Hi cellardoor,
I have the same problem on my W126 sedan, so your post is most helpful - cheers mate
My only concern is the silver trim, is this attached with (frail) plastic clips, or can it simlpy be gently pried of after removing the covering pieces in the corners/top?

Btw., if the rust bites all the way through at the rear window, then a body repair part exist. I've seen it on the net (can send you a link if needed) - also, members Andy and Andy420 has discussed it in this post: http://forums.mercedesclub.org.uk/showthread.php?t=235&highlight=rear+window

Thanks,
Hans

I believe this is a comon problem, if you have only just now sorted it, check the rot on the rear shelf..

I have a leak on my W123
Tried sealing it but no luck.
How did you get the trim back on?
From other posts, it says these should be fitted to the rubber seal and glass before it is fitted to the car.
