Aluminum resists corrosion. Therefore aluminum wheels do not need painting for most operating conditions. Wash the aluminum wheels when you wash the vehicle. Do NOT use highly alkaline cleaning agents.

Certain environments created by some operations may lead to aluminum wheel corrosion. Some of these operations include the following conditions:

    • Livestock hauling
    • Snow removal using salt or chloride compounds
    • Using highly alkaline cleaning agents

If these operating conditions exist, clean the wheels often with a stream of high-pressure water and mild detergent. Whenever you remove the tires, thoroughly clean the wheels.

Various protective coatings give good results. When using a protective coating, refer to the following suggested procedures:

  1. Use a general purpose pad (such as 3M Scotch-Brite® No. 7447), or use a buffing wheel and a medium abrasive rubbing compound (such as 3M No. 05979 Clean-N-Glaze™). Aggressively rub the machined surfaces in order to remove some of the corrosion and to restore most of the luster.
  2. Wipe the surface with aluminum cleaner-polish (such as Mag Wheel Cleaner Polish™ Stock No. PGC) in order to obtain maximum luster.
  3. Clean the wheel with silicone remover (such as 3M No. 08984 General Purpose Adhesive Cleaner and Wax Remover™, or Prep-Sol®). Wash the wheel with clean water and dry with compressed air.
  4. Wipe the wheel again with aluminum cleaner-polish. Apply a metal preparation (such as C.I.L. Metal Prep. No. 33 for aluminum) following manufacturer's instructions.
  5. Apply a zinc chromate primer in four light applications, rotating the wheel 90 degrees between applications.
  6. Spray the wheel with two light coats of wheel protectant (such as Coricone 1700 Clear Metal Protectant™ Stock Code DDC).
