Matte Paint Care Guide
■Materials that may become difficult to remove
The following are likely to settle into the vehicle body and should be cleaned off immedi-
ately.
●Rain water, sea water, and other liquids that may cause water stains
●Sand, pollen, volcanic ash, and other particulate matter
●Dead insects, bird droppings, etc.
●Sap, leaves, flowers, etc.
●Mud, snow, anti-freezing agents, and other road debris
●Gasoline, engine oil, asphalt, and other oily materials
■Do not wax or apply a coating to the vehicle
Do not wax the vehicle or apply a coating to the
vehicle body, as they will form a film over the
painted surfaces, filling the matte clear coat sur-
face, making it more flat. As a result, it will
become more glossy, possibly permanently los-
ing its matte properties.

Matte Paint Care Guide
●Dead insects, bird droppings, and oil stains
If these materials are not cleaned off, contaminants, such as proteins and oil, may settle
into the textured surface of the matte clear coat, making it difficult to clean off with
water alone.
Create a thick lather with the solution.
Thoroughly soak a soft chamois cloth in the
neutral detergent solution, covering it in the
lather, and place the chamois cloth over the
dirty area. Wait for the contaminants to be
dissolved by the solution. Then, gently wipe
the area several times with the chamois cloth,
taking care to not rub the vehicle body. After
that, apply plenty of water to the area wash off
the dirt and detergent solution.

may settle into the matte clear coat, making it more

permanently losing its matte properties.
