PROBLEM TO BE SOLVED: To obtain the subject composition having excellent luster, water repellency, capable of simply removing stain even if the composition becomes dirty after use for a long period of time, useful for a body of automobile by making the composition include a copolymer composed of a polymerizable unsaturated carboxylic acid, etc., and a specific fatty acid. SOLUTION: This composition comprises (A) (i) a polymerizable unsaturated carboxylic acid such as methacrylic acid, (ii) a (meth)acrylic acid ester containing a 1-8C alkyl at an ester part (e.g. butyl methacrylate) and (iii) a dimethylpolysiloxane of formula I or formula II (R1 is H or the like; R2 is a 1-6C alkylene or the like; R3 is a 1-6C alkyl or the like; (a) is 5-300; A is O or the like; b is 0-6; c is 5-300) in the ratio of preferably 15-70 wt.% of the component (i), 10-50 wt.% of the component (ii) and 10-70 wt.% of the component (iii) and (B) a 18-36C fatty acid such as stearic acid preferably in the weight ratio of 30-70:70-30.
