Hi Martin I found this perhaps it is of interest to you === The metal part of the windscreen trim is in two parts and simply clips into plastic trims which are spread around the windscreen. On mine the rubber was attached to the metal windscreen trim and came away with it. I used special rust treatment to eat all the rust away and after priming and top coating it has not come back to date. A couple of months after doing this a stone came up and cracked the screen but fortunately my insurance covered the replacement. The trim and rubber were replaced at the same time. They came separately and the rubber just pushed onto either side of the metal part of the trim. A word of warning, when they took the screen out it was found that rust had got underneath the edge of the screen itself and the fitter advised that it would be best to ensure all the rust be removed otherwise the new screen would not bond to the body. Apparently if there are any points where the screen does not bond correctly it will cause a stress point and the screen will crack. I completely removed all the rust and re-painted the edge and they came back and refitted the screen. I now have no rust, a new screen,new trim and rubbers and no problems. With hindsight I would definitely say it is best to have the screen removed as it difficult to see how far the rust has penetrated. Though I must say that in your case the rust doesn't look too bad. Moral of the story is wait until a stone cracks your screen and make sure you are insured. I wish the stone had cracked my screen first it would have been a lot easier. Never mind at least I got a good job done in the end. I tried to upload some pics I took of the process but they were too large. Let me know if they would be useful and I will attempt to downsize them. Good luck with your rust removal. Frank XK8 Coupe 2000 4.0L V8
