To provide a weather-resistant coating composition excellent in thick-film coating property, from which a coating film having excellent long-term weather resistance can be formed.
The weather-resistant coating composition is a multi-component composition comprising a main agent (I) and a curing agent (II). The main agent (I) includes an acrylic resin (A) having both of fluorine and a hydrolyzable silyl group, and a hydrolyzable silyl group-containing silicone resin (B). The curing agent (II) includes a catalyst that promotes polycondensation of a hydrolyzable silyl group. The resin (A) includes, on the basis of the whole monomer units, a fluorine-containing polymerizable unsaturated compound (a1) by 1 to 80 mass%, a hydrolyzable silyl group-containing polymerizable unsaturated compound (a2) by 1 to 50 mass%, and a (meth)acryloyl group-containing compound (a3) by 1 to 90 mass%.
