What tools can I use to apply and burnish my foil?

Scrubbing (polyester or nylon) bristle brushes work best with foils. Examples of these types of brushes: Toothbrushes (soft or medium), household hand scrubbing brush, or manicure brush (soft and flexible). Make sure bristles are not too stiff so the painted finish isn’t damaged. Wire or Steel scrubbies are not recommended.
