Abstract: To provide a technique of continuously imparting favorable water-repellent performance to a vehicle exterior member for a long period.
A method for setting a condition for recoating a vehicle exterior member with a water-repellent coating film, the method including:



a peeling step of peeling a water-repellent coating film formed on a surface of the vehicle exterior member;
a recoating step of forming a water-repellent coating film onto the surface to obtain a coating-film-formed vehicle exterior member, the recoating step being subsequent to the peeling step; and
an assessment step of adhering a test liquid drop onto the water-repellent coating film formed through the recoating step, and making a water-repellency assessment, wherein
the assessment step includes making, when a fall-off angle of the test liquid drop is not greater than 20°, an assessment that a recoating condition used in the peeling step and the recoating step is an acceptable recoating condition.

Abstract: A silver mirror film includes a plurality of silver particles arranged in a film surface direction, a plurality of interparticle silicon particles between the silver particles, and a plurality of surface silicon particles on surfaces of the silver particles so as to at least partially cover the surfaces. The interparticle silicon particles and the surface silicon particles are present as (SixO2y)n{x≥1, y≥1, and n≥1}.
