I dont have any experience with these very alu foils.
But in general, I would be very very careful almost scared, to bend the precise bent spot back again, when talking about hardened aluminium.
Aluminium will harden when bend or local pressure points, and if bend several times it might simply weaken and break at next impact, or even break fully in two if bend a lot.
Of course it might need to be bend a lot more for real damage, and maybe no problem with a small re-adjustment.
But if you aim for the very precise spot, to get it "perfectly right", it might be a serious weakening, and a lot worse than just righting the full part roughly.
Dont know, but would be sceptical, unless some has bend one a lot back and forth and being able to test it has not been weakened when getting too hard (deformation hardening is the expression in our language)
