You can rejuvenate the appearance of your windshield wiper arms by refinishing them with the appropriate paint. Windshield wiper arms are composed of metal, a surface ill-suited for paint adhesion. You must pretreat the arms by applying special acidic primer, formulated with the ability to etch durable metal. In addition, you should choose a certain type of paint that will provide an attractive glossy sheen and remain durable in varying weather conditions.

Instructions

  1. 1

    Remove the windshield wiper blades from the wiper arms.

  2. 2

    Clean the windshield wiper arms with a trisodium phosphate cleanser, using steel wool. Rinse the arms, using a water hose. Wait two to four hours for the entire automobile to dry.

  3. 3

    Protect the automobile from paint over spray by covering it with plastic dust sheets, masking paper and painter's tape.

  4. 4

    Coat the clean wiper arms with galvanised metal etching spray primer. Maintain an eight-inch distance between the wiper arms and spray nozzle as you apply. Wait four hours for the primed arms to dry.

  5. 5

    Coat the primed wiper arms with an oil-based spray enamel. Maintain an eight-inch distance between the wiper arms and spray nozzle as you apply. Wait four hours before reattaching the wiper blades.

Tips and warnings

  • Add a second coat of enamel only if the primer shows through.
  • Do not use oil-based, latex or acrylic primer on windshield wiper arms, or the finish will eventually shed.
  • Do not use a latex or acrylic paint on windshield wiper arms, or the finish will eventually flake.
