DO NOT GLUE.. I have used all the Major names ... Fusor.. 3M.. Duramix... SEM. All of them will hold the panel on, BUT the repair will pull a line where the patch is at,
especially when in the sun. I have seen cars where guys have glued aftermarket skins at the top of the body line,, results are poor, you can see a seam, sorta like 70's
Vettes.
Glue is used for holding around the wheelhouse, front leading edge of a quarter where it wraps around inside the door jamb, along the rear by the trunk floor extension,
or if you are installing a full door skin. Even in these instances I still put a few tacks with a mig just to ensure no failure.
