I researched it quite a bit as it gained popularity with the collision repair guys. A friend of mine was a pretty big fan of the adhesives out of the gates. But I've talked to too many in the classic restoration field that have regrets about trying it on large panel seams.
Mostly to do with darker cars like black cars soaking up heat in the sun and thermal expansion incompatibilities. Basically the seam mysteriously showing itself in certain conditions.
I don't mind the old school methods.
Especially since the entire body of this car is basically critical torque structure which is important when you plant 400 + HP to a pair of sticky tires and the engine tries to lift the drivers side engine mount at the same time it pushes down on the passenger side and it basically tries to twist the car like a beer can. (I don't quite make 400 HP right now but it would be pretty damn easy for me to get there with a few bucks)
