Abstract: In a coating, line a first substrate such as a vehicle body, made of a steel plate, is coated separately from a second substrate made of a different material including a plastic, such as vehicle parts, i.e., bumpers and so on, and the parts are assembled with the vehicle body. The vehicle body and parts are coated separately to form each a highly reflective surface coating. The coating is implemented by a spraying step for spraying the paint on them to form a coat; and a drying step for drying the coat. The paint is sprayed in the spraying step in a film thickness which is thicker than a thickness at which the paint sags on a surface extending at least upwardly and downwardly.

Abstract: In the coating method containing a coating step for coating a substrate with a paint and a drying step for drying the paint coated thereon, the paint is sprayed on a side extending in an up-and-downward direction and a side extending a horizontal direction in the coating step in such a manner that it is coated in a given film thickness on the horizontally extending side and in a film thickness on the up-and-downwardly extending side, which is thicker than its sagging limit thickness in which it sags. The coating is effected such that the coating on the up-and-downwardly extending side is finished at the same time as or subsequent to the coating on the horizontally extending side.In the drying step, the substrate is rotation about its horizontal axis extending in a horizontal and longitudinal direction of the substrate during a period of time from before the paint sags to until it is cured to a sagless state.

Abstract: Disclosed is a coating method involving a coating step step and a drying step, in which the substrate is sprayed with a paint on its surface extending substantially upwardly and downwardly with the paint to form a coat in a thickness thicker than a thickness at which the paint starts sagging in the coating step and the coat formed on the substrate is dried at the drying step by rotating the substrate about its axis extending in a substantially horizontal and longitudinal direction of the substrate for a period of time ranging from the time when the paint coated starts sagging on the surface of the substrate extending substantially upwardly and downwardly to the time when the paint of the coated formed thereon achieves a substantially sagless state, the rotation of the substrate sprayed with the paint thereon being carried out at a speed which is high enough to rotate the substrate from a vertical position to a horizontal position before the paint coated thereon substantially sags due to gravity yet which is l

Abstract: A highly reflective surface coating is formed by spraying a paint on a substrate as a vehicle body in a thickness thicker than a thickness at which the paint sags and rotating the substrate about its horizontal axis at a speed between a lower limit and an upper limit in order to cause no sagging until the paint sprayed is cured to a sagless state.Before the paint is sprayed in that thickness, an edge portion of the substrate is lowered than other portions thereof, thus preventing a mass of the paint from swelling on a top coat at its edge portion and providing a good appearance on the surface coating.The lowering of the edge portion thereof is effected by lowering the substrate itself without any coat or by spraying the edge portion in a film thickness thinner than the other portion thereof.The coat sprayed with a paint containing a volatilizable solvent may be dried through sequential setting and baking steps, while a powder paint sprayed may be baked without setting.

Abstract: A coating method contains a coating step for spraying the surface of a coating substrate paint with a paint and a drying step for drying the paint coated thereon. The paint coated on the substate is then caused to flow or sag artificially within the coat in the drying step by application of an action from the outside at least in one of the coating and drying steps, namely, by heating or vibrating the paint coated thereon. During the flowing or sagging of the paint artificially, the substrate is rotated about its axis extending substantially horizontally in a longitudinal direction of the substrate at a speed which is high enough to rotate the substrate before the paint coated thereon substantially sag due to gravity yet which is low enough so as to cause no sagging as a result of centrifugal force.

Abstract: The coating method includes the intercoating step for spraying the intercoating paint over a substrate after undercoating, the intercoat drying step for drying the intercoat on the substrate, the overcoating step for spraying the overcoating paint over the dried intercoat on the substrate, and the overcoat drying step for drying the overcoat. In the intercoating step, the intercoating paint is sprayed in such an amount as causing sag, that is, in an amount beyond its sagging threshold value. In the intercoat drying step, the substrate is rotated about its horizontal and longitudinal axis to dry the intercoat.
