Panel adhesives are actually the best when it comes to corrosion issues. I weld my patch panels though as all of the actual patches I do are never perfect fits. I always have to tack and tweak and tap and tack. With glue you would need a very near perfect fit. I would also be concerned that on mid panel patch seams the seam line might telegraph through with the glue. For OEM panel replacement, door skins, etc on non structural areas glue would be the way to go no question.
