"I had my windscreen replaced as part of the roadworthy with a new laminated one.
Part of the replacement was a new windscreen rubber.
My word of caution-
The new rubber fit ok, however it was smaller, in that it covered less steel (radiating out from the glass {best description}) than the old one.
No big deal really, except that there is a line where the paint was covered up before, and exposed now."
Maybe the replacement windscreen itself may be smaller than the previous windscreen and not stretching the seal out far enough.
Easy fix is, from the outside of the car, to poke in a piece of insulated electrical cable between the edge of the windscreen and the seal to push the seal out further. Do this with the windscreen fitted. Do one edge of the screen at a time. Easy to remove if doesn't work.
