I had a new rear windscreen fitted on the insurance and it's leaking. I've got the makers workshop manual and that says to use sealer between window and rubber when fitting the rubber to the screen, and then sealer (obviously) between rubber and body. I watched the fitter at work and he didn't use any between glass and rubber. Now if it's needed with a new rubber surely even more necessary with an old one?
Obviously I will complain to the company, but don't want some temporary bodge done. So does anyone know what the correct way is these days with the type that has a separate rubber seal?
