PROBLEM TO BE SOLVED: To provide a coating agent for coated surface of a vehicle body having dramatically high water-repellency and high oil repellency and capable of forming a perfluoropolyether-modified coating film having extremely high antifouling property on a coated film, accordingly.SOLUTION: There is provided a coating agent for coating a coated surface of a vehicle body to form a perfluoropolyether-modified coating film on a coated film including one or more solvents selected from m-xylene hexafluoride, fluorine-based solvents, dimethylpolysiloxane, cyclic siloxane, alcohol-based solvents, glycol-based solvents, acetone, aliphatic hydrocarbons and aromatic hydrocarbons, by meas of a perfluoropolyether-modified polysilazane expressed by general formula F(CFO)CF-Q-Si(NH)(in the formula, Q is a bivalent organic group; m is an integer of ≥1; and x and y are each an integer of 1-3). |
