The metallic paint effect of the yacht model is the key to reflecting its real texture and craftsmanship, and the color layered spraying technology is the core method to achieve this effect. By simulating the reflection and refraction characteristics of the metal surface, combined with the superposition and gradient processing of multiple layers of paint, the model can present a realistic metallic luster.
The realism of the metallic paint surface starts with the bottom layer treatment. First, spray black or dark gray primer evenly on the surface of the yacht model to enhance the hiding power and layering of the subsequent coating. After the primer dries, use fine sandpaper (such as 1200 mesh) to lightly polish it to remove surface particles and ensure that the primer is flat and smooth. This step provides the basis for the subsequent adhesion and gloss performance of the metallic paint.
The metallic paint layer is the core of the glossy texture. Choose high-purity aluminum powder or silver powder metallic paint, and use the spray gun to evenly cover the primer in a "thin spray multiple times" manner. When spraying, keep the gun distance about 15-20 cm, and control the air pressure at 0.2-0.3 MPa to avoid paint accumulation or sagging. After the first layer of metallic paint dries, the spraying angle can be increased appropriately (such as 45-degree tilted spraying) to simulate the irregular reflection of the metal surface.
After the metallic paint layer dries, spray 1-2 layers of clear varnish to form a protective layer and enhance the gloss. The clear varnish needs to be high-gloss, and the air pressure during spraying is slightly lower than the metallic paint layer (about 0.15-0.2 MPa) to form a uniform mirror effect. After each layer of varnish dries, it can be lightly sanded with fine sandpaper to remove surface defects and provide a smoother base for the next layer.
To increase the sense of reality, the oxidation or wear of the metal can be simulated by color gradient technology. Between the metallic paint layer and the varnish layer, spray a light gray or copper gradient paint locally, use masking tape or sponge to dip a small amount of paint, and dab it on the edge or protruding part of the model to form a natural transition oxidation effect. This step requires careful control of the amount of paint to avoid over-covering the metallic luster.
Use high-gloss paint and shadow paint to further enhance the three-dimensional effect. Spray a small amount of white or silver high-gloss paint on the bright areas of the yacht model (such as the bow and the edge of the porthole), and spray dark gray shadow paint on the recessed or shadowed areas (such as the seams of the hull). Use an extremely fine spray brush to control the amount of paint and create subtle changes in light and shadow.
After spraying, use a polish or metal wax to grind and polish the surface. Choose a fine-grained polish (such as 2000 mesh) and gently rub the surface in a circular motion to remove small particles of the varnish layer and improve the gloss. After polishing, dip a small amount of metal wax with a soft cloth and apply it evenly on the surface to form a protective film and enhance the reflective effect.
To simulate the use of the yacht in seawater, spray a small amount of light blue or green transparent paint on the surface of the model to simulate the corrosion effect of seawater. In addition, use fine sandpaper or steel wool to create slight scratches in specific areas (such as the bottom of the boat and propeller) to increase the sense of reality. These details need to be coordinated with the overall style to avoid excessive damage to the metal luster.
Through color layered spraying technology, yacht model can achieve a texture leap from the bottom layer to the surface layer. From the smoothing of the primer to the gloss construction of the metallic paint, to the superposition of the transparent varnish and the simulation of the gradient effect, each step requires fine control. Combined with highlights, shadows and surface treatment, the final metallic paint surface not only has a real gloss, but also contains delicate layers and details.
