(11) Creeping: The phenomenon that the wet paint film spreads naturally beyond the original paint area.
(12) Missing application area; Missing application point (Miss; holidays): A pathological state where paint film is not formed at all in some areas that should be painted. This is usually caused by an improper painting operation.
(13) Lapping defect: In the painting process on the same day, because of the different painting sequence, there is a raised phenomenon at the edge junction of each paint area on the bottom village.
(14) Lifting: When the same or different coatings are applied to the paint film, the dry paint film at the lower part of the paint film softens, bulges or detaches from the substrate during the application or drying of the coating. Phenomenon (usual appearance such as wrinkling).
(15) Piling: A paint that dries quickly. During the brushing operation, it becomes very viscous, resulting in uneven paint film thickness.
(16) Bleeding: The colored substance from the lower layer (substrate or paint film) enters and passes through the diffusion process of the upper paint film, thus causing the paint film to exhibit unwanted coloring or discoloration.
(17) No-hiding; show-through: The color paint applied to the bottom surface (whether or not painted), reveals the color of the bottom surface after drying.
(18) Residual tack: Residual tack: A sick state in which the viscosity of the paint film remains after drying (curing).
(19) Flashing: The phenomenon that the gloss of local paint film (especially at the junction) is higher than that of the overall paint film. Usually caused by uneven paint film thickness.
(20) Exudation; Sweating: The phenomenon that one or more components of the paint base are precipitated on the surface of the paint film. The exudate was oily and sticky.
