Any help appreciated, have recently had the car resprayed currently re-fitting rear windows (its a coupe) thye metal window surround is meant to push in between the window seal but i cant for the life of me get it to locate in the channel. Is there a knack to this ie taking window out and fitting surround then re-fit to car, any help, tips, opinions welcomed!!

Black rubber ones can be refitted with a couple of screwdrivers, at great risk to the paintwork, but, if it's the metal type filler, then you really need to get the special tool for the job.

take the window out and u can then bend the rubber and push the metal frame ting in
i spent hours trying to do it wit the window in and wen i took it out it took 10 min

thanks for help guys i think taking the window out seems the most sensible option.

The correct tool to do this costs next to nothing and takes about 10 minutes
