I guess if there were no replacement rubbers available I’d have simply made do with putting some sealant mastic between the glass and rubber edge and hoping it stopped the leak..,
The original jaguar rubbers had volcanised corner joins, but the process of reverse engineering those would have made each rubber 10 times the price that I was able to get them made with industrial strength glued joints by the rubber specialist company.
The first step was to remove the original window rubbers. This was done by running a sharp knife along the glass and through the rubber itself around the window, and then carefully to push the glass itself out from the inside of the car. Then the remaining rubber was pulled from the car window opening, and old mastic removed from the bodywork and the glass itself.
The glass itself simply fitted into the groove around the inner edge of the new rubber – the rubber being stretched slightly to get the last corner of glass to fit into it.
The cord went further round itself a little way and was tucked into again between the glass and rubber (so that it didn’t drop out when handled).
Then, working from inside of the car while pressure was maintained on pushing the glass into the car, the cord was pulled from it’s groove – this had the effect of pulling the rubber itself up and over the bodywork lip and drop back in place. The cord was pulled off around the windows glass all the way round in one motion until all the rubber had been pulled over the bodywork lip and the window was fully held in place.
Once the window with its new rubbers was firmly seated into the bodywork (which took a couple of hefty thumps of the glass to fully seat the rubber) a thin bead of mastic was squirted between the glass and the rubber.
Once any excess was cleaned off the final fettling of the rubber along the chrome strip was carried out.
After some final cleaning up of finger prints off the glass and body work the job was done
