I used percisely the HobbyTown bare metal foil in your photo to 'freshen up' a small part in my instrument cluster.
There was some leftover old chrome plating on the plastic piece, but I scotchbrited it smooth and cleaned with alcohol before applying the foil. It looked fabulous for 3 months, now the underlying old plating I left on the part is delaminating under the new baremetal foil and telescoping through it.
Advice: I think it would work, but get rid of ALL the old plating and apply only to a fresh surface.
