Hi all, has anyone got experience of renewing the rubber strip across top of the windscreen on a Zafira?......can this be a d.i.y. job, or are special tools etc. required.?.......mine is badly distorted and wont lie flush with roof. I know the w/screen is bonded on to these cars,and there`s no water coming in,....it just looks unsightly!.........TIA for any advice Doug.
