This was posted on the Hamb 52-59 social club. It's a link to a Hotrod magazine article/photos on a project using EMS repair panels on a '57 conv.

Thats a pretty good article. From what I see the EMS panel they were installing would be a good candidate for that 3m panel bond. It already has the flange
built in for the adhesive. I'm seriously going to be looking at panel bond for a floorpan and tailgate panel repair on another vehicle I'm fixing.
