Hey ladies and gents, my 09 451 needs the panoramic roof replaced and I've read that it requires a special kit including a primer and adhesive. The kit is OEM Smart Car Fortwo Panoramic Roof Adhesive Glue Set - CODE E22 OEM A4519890071... However the kit seems to be discontinued and I can't find it anywhere. I've located the adhesive but I can't find any info on the primer to be used. Anyone have any ideas? Thanks in advance.
