hot to the touch. This will streak the finish. DO NOT wipe dirt off
dry surfaces, as this will scratch the finish.

areas (salt water and high humidity atmosphere) or other
areas of corrosive environment, paint and bright metal may
require frequent washing and waxing to prevent deterioration.
Determining washing frequency is the customers responsibility.
NOTE: For vehicles exposed to ultraviolet rays of the sun, apply
a coating of Bon-Ami® soap, or similar product, to the inside
surfaces of the windshield and windows, to shade the interior
and prevent fading of the interior trim.
