PURPOSE: To prepare polishing agent for vehicle having extremely excellent characteristics, e.g. greatly improved physical properties such as luster durability, water repellency durability and stain resistance, excellent workability, ready coating performance and wiping properties and almost no adhesion as an oil film to the face of window glass.
CONSTITUTION: A coating film-forming component composition comprising a higher saturated fatty acid fluorine-containing aliphatic alkyl ester and a silicone oil in a proper blending ratio is dissolved in a proper solvent, emulsified or decomposed. A higher saturated fatty acid fluorine-containing aliphatic alkyl ester obtained by esterifying a ≥18C saturated fatty acid and a 2-18C fluoro- alcohol is preferable as the higher saturated fatty acid fluorine-containing aliphatic alkyl ester.
