And yet 24 years later they still dont glue on quarter panels and boxsides and again for the most parts a crash is energy absorption designed in thats why the call the different parts of the vehicle crumple zones and crush points. Yes there is some stretching and shear but usually after massive crushing and deformation, a few reasons domestic oem dont ise it is because they have designed the vehicle to absorb energy in a controlled manner where temperature and other influences that can change the glues properties and make the crash not repeatable, when I do any panel I use a piece of masking tape and before I remove the panel I mark every spot weld with a sharpie and transfer the tape to the new panel so I have the exact amount of spot welds exacty where the manufacturer wants them, one thing I was taught over the years was to “not kill the baby” wether in you vehicle or the one next to you , glueing a panel on is not making it pre accident condition it alters it and it may not crash exactly the way the manufacturer wants, it has its place for composites and places that have been tested and approved by the oem, not by the glue manufacturing, again use it for cab corners use it to glue on you patch panels, Ill stick to what I know works, and half the time someone is shrinking a panel is because they beat the shit out of it with their hammer on dolly smashing technique. Anyways Ill weld and use adhesives where the oem does but I will use the proven method the oem uses. Im not going to be responsible for killing anyone because I want to save time or cut a corner.
