The rubber trim in the wheel well of my sister’s car separated from the steel frame. What’s the best way to reattach it?

Obviously I’ll clean the steel and rubber with soap and water, and probably use some kind of adhesive. I know it needs to be weather proof and vibration proof. I was thinking construction adhesive, but I think that would fail the vibration test. Then I thought epoxy, but standard epoxy would probably have the same issue. What about steel reinforced epoxy?

Any other suggestions? Should I use an abbrasive like steel wool?
