CARE OF EXTERIOR FINISHES (CLEANING AND POLISHING RECOMMENDATIONS).
APPLICATIONS:
ALL CARS AND TRUCKS WITH BASECOAT/CLEARCOAT PAINT FINISHES (EXCLUDES S/T TRUCK)
Today's basecoat/clearcoat paint finishes are very different from materials used on vehicles in the 1980's.
Materials, procedures and equipment which once worked well for polishing traditional finishes may not be acceptable for use on basecoat/clearcoat paint
surfaces. The use of outdated materials, procedures and equipment may produce what appears to be acceptable results under shop lighting, but will be
unacceptable to the customer when the finish is exposed to sunlight (typically, swirl marks).
While the following information can be most helpful in the new car "prep" area, it should also be made available to the "used car" area and the collision/
paint repair area.
KEEP THE VEHICLE CLEAN AND DRY
-
Avoid washing vehicles in direct sunlight.
-
Avoid using strong soaps or chemical detergents.
-
Use "brushless" type automatic car wash equipment.
-
Avoid using products containing acids (unless specified to correct a condition such as "rail dust").
-
Don't use brushes or brooms to remove snow or ice from vehicles in storage or on lots.
-
Cleaning agents and water should be dried promptly and not allowed to dry on the surface.
-
Standing rinse water should be dried promptly and not allowed to dry on the surface.
-
Drying with a soft chamois is recommended.
DON'T CREATE A PROBLEM
