This type of finish makes it possible to achieve a more attractive and striking effect against the reflection of UV rays.
Initially used in high-end models due to its high cost, metallic paints for cars are chosen due to their visual appeal as a result of the reflection of light on the small particles mixed with the paint.
Metallic paint is divided according to the type of colors that are chosen, and can be divided into metallic, pearl and special. Its classification will depend on the pigments that make up the paint and the particles that include its composition.
This type of finish is produced thanks to acrylic enamels, which since their inclusion in car paint allowed the colorimetry of cars to be considerably expanded.
Thus, metallic paints are acrylic-based and are applied with bilayer or trilayer systems in order to seal the surface and obtain a finish that stands out in sunlight.
How is metallic paint applied?
Special particles are one of the most striking finishes in metallic paints thanks to the pigments used in their manufacture, better known as colorstream.
These are made up of sheets of silicon dioxide coated with metallic oxide that allow different shades of colors to be reflected and achieve a polychromatic effect.
Advantages and disadvantages of metallic paint
Metallic paint is a type of compound to which small metal particles have been added to produce a shiny effect. The amount of particles added will directly influence the color.
One of the advantages of metallic paint is to provide greater protection against possible friction and scratches. The finish of this paint makes it possible to better hide this type of damage to the car, added to the fact that it also has greater protection against discoloration caused by UV rays.
On the other hand, one of the main disadvantages of this type of paint is the cost. As it has a much more complex composition than the usual paint, both its production and maintenance costs are considerably higher than the rest of the finishes.
Metallic paint for cars: how to use them
Metallic paints should be used with greater care than solid ones, since the delicacy with which it is applied to the car will directly influence the effect achieved in the end. Therefore, primers should be evaluated in a light that resembles sunlight to analyze the effect.
One of the best ways to find out what colors to use is to check with the car manual, or by contacting one of the official dealerships of the car brand. In addition, the catalysts and diluents must be adapted so that the metallic particles are better coupled.
Another of the key points to know how to use metallic paint is its blending. This technique allows the paint to completely cover everything, with the particles distributed throughout the car. It is recommended to orient the gun so that the spray impacts the surface regularly.
Types of paint and finishes
Polyurethane is a type of paint that has pigments, catalyst enamel, hardener and ultraviolet ray protection filters. The durability will depend on the type of use that is given to the vehicle, although its protective filters allow it to have a greater tolerance to the sun.
For its part, polyester dries quickly in approximately 10 to 30 minutes and provides a rather opaque finish, both in solid and pearl types of paint. In addition, it is important to have polyurethane diluent for its application.
In turn, acrylic paint is one of the most chosen thanks to its long life since it is one of the most resistant to damage. Although it gives a great shine to the car, one of its main flaws is the long drying time it takes.

The types of paints also have different finishes: solid, metallic, pearl or matte.
