You have nothing to worry about when it say's glue'n. Trust me the stuff the body shop's use, is not your ordinary glue!! They glue roof's on car's, They glue bed side's on Pick up's That glue is stronger than spot welding!
If your worried about the panel be'n messed up cause of the glue than that is a valid concern, other than that, optimus Prime couldn't even pull that glue apart!
