What can I do to make the wheel wells?

You could use a pressure washer to clean the wheel wells. Some wheel wells are plastic, while others are metal. Plastic style wheel wells may just need a good cleaning. Undercoating sprays or brush on products can be purchased at your local auto parts store to protect metal wheel wells from rusting. If you use a spray type product, be sure to mask off your car's painted areas to prevent overspray.
