3m uses a special gun for body panel adhesive.
i have been using panel adhesive sense it hit the market, both 3M and Norton. i have had problems with the bonded seam showing up on more than 1 job.



so have I, I no longer use it on exterior seams, and it's not really meant to be used as a stand alone, weld corners etc. Park in sun seam shows up , back inside the seam lays back down. that was with 3M, once digging that stuff back out was enough for me.
