My parents just bought a really nice low mileage 99 E300 but the fabric on the headliner has separated from the backing board. We intend to remove the entire headliner and re-glue the fabric to the board using the proper 3M spray adhesive.

Any suggestions on how to go about doing this? I have never worked on a Mercedes before so I am not familiar with any of the interior trim. We will not pay a shop to do this.

Thanks
