Dampen a rag with soapy water and wipe down the affected chrome. Remove any loose chrome or rust with a wire brush.
Rinse the chrome with plain water and dry with a separate rag. Cover the scuff with a thin layer of self-etching primer with a natural-bristled paintbrush. Allow the primer to dry at least eight hours, or overnight, before continuing.
Slip on a pair of rubber gloves and safety goggles before shaking the can of chrome spray paint for at least 30 seconds. Holding the spray can at least 10 to 12 inches away from the chrome surface, cover the primed area with a thin layer of the chrome paint.
Allow the chrome paint to dry for at least four hours before applying a second thin layer. Allow the final layer of chrome paint to dry at least eight hours, or overnight, before continuing.
Cover the chrome piece with a single layer of clear coat protectant. Apply the clear coat with a natural-bristled paintbrush and allow it to dry for at least eight hours before using the piece.
