This is the Bare Metal Foil - Matte Aluminum

Bare Metal Foil is adhesive backed real metal, only .0005 inch thick. It's easy to apply, conforms to all curvatures and allows details to show through.

To use, cut a piece from the sheet slightly larger than the part to be covered. Burnish with cotton swab or soft cloth. Then trim excess with a sharpno.11 blade.
