Rubber door strips

[Captain Stubing]

My dad has a REAL nice EL Falcon, Tickford suspension, immaculate condition, think it's called emerald green in colour. He's the second owner, and knew the first owner, and both have always looked after this car.
Last year, he got to be the meat in the sandwich... Energex truck up the date, pushing him into the car in front. The car's been repaired, but now the wide rubber strip on the left front door doesn't stay stuck to the door.

Does anyone know a good sticking product, that will make this strip mate with the door? He's tried a few things that haven't worked, but I think it's little problems like this that'll make him change cars.... :eclipsee_
