This is very good stuff, Warning! if you use this you will never get the two pieces apart without distructon..........of one or both pannels!


Judging from its tensile strength/temperature curve, it can be disassembled by using a heat gun.
 
I’ve used 3M 6504 Marine Adhesive Sealant recently. It’s good stuff if it will be in the splash/wet areas of the car. Check to see on any product of how compatible it will be with the paint or coating product that may be used with it. If you are leaving it raw aluminum look then I have had good luck with 100% silicon RTV as it’s easy to apply and blends & less noticeable and you have a chance at replacing a panel without destroying it.
 
I've used quite a bit of Loctite AA H8000 Methacrylate Adhesive on my scratch-built Miura project. Easy to use with 30 minute working time. High tensile strength but can be separated with a heat gun or other high heat source. So good for all parts of a car except where there is high heat in proximity of the bonded panels. It used to be called Aluminum Panel Bonder but I'm guessing they changed to name because it is useful for bonding several other materials beyond aluminum.
 
PPG PR-1440, technically considered a sealant. Used in aircraft between panels, has excellent bonding strength, also allows for continuity from panel to panel.

Pricey, can be used be purchased in pints or 6 oz mix tubes.

Tons of variations on the products:
Examples:
1440 - fuel tolerating
1422 - structural
1750 - high temperature

Been using it for 20 years... and never failed me.

Used it to install 90-degree L on the top of radiator, to hold fan mounts:
