Abstract:
A clear coating method comprising: applying a clear paint on a topcoat base coating film (21) under a first coating condition, and thereby forming a first wet clear coating film in a first stage (14A); successively applying a clear paint on the first wet clear coating film under a second coating condition different from the first coating condition without baking the first wet clear coating film, and thereby forming a second wet clear coating film in a second stage (14B); and baking the first wet clear coating film and the second wet clear coating film and thereby forming a clear coating film, wherein a painted non-volatility value of the clear paint in the second stage is larger than a painted non-volatility value of the clear paint in the first stage, an average atomized paint particle size of the clear paint in the second stage is smaller than an average atomized paint particle size of the clear paint in the first stage, and a thickness of the second wet clear coating film is thinner than a thickness of the first wet clear coating film.
