Chic, shine, beauty with canned chrome paint
There are several ways to create chrome finishes on car surfaces. The simplest of them is spray chrome paint in cans, the advantages and disadvantages of which we will consider in this article.
Chrome compounds in cans are aerosol paints. Due to the advantages discussed below, these paints and varnishes have become widespread, including in the field of car painting.
This is primarily due to the ease of use:
- Firstly, this material does not need to be diluted with a solvent before use.
- Secondly, spray cans for such paint are themselves tools for application, therefore, an airbrush and other equipment are not needed, therefore, aerosol materials eliminate all the problems associated with the operation and maintenance of tools. In addition, applying the material in cans is much easier than working with a paint sprayer, it is especially convenient for them to process hard-to-reach places.
- Thirdly, aerosol paints and varnishes are characterized by many positive functional and aesthetic qualities, such as brightness, resistance to environmental factors, environmental friendliness, ease of storage, easy removal.
However, such paints also have some disadvantages. These include the inability to create a clear border without a stencil, flammability, the inability to mix, the tendency to bleed. In addition, no application instructions are provided for such paint, so users have to look for advice or act on their own.
In addition, it is possible that the paint will turn out to be the wrong shade that it should be, or not suitable in quality, so you should first check it on any metal surface.
It is advisable to purchase materials from the same batch, since paints of the same color, not only from different manufacturers, but even from different batches, can vary in shade. Also, many users note a large consumption of material.
It should be borne in mind that spray paint is usually not used for either full or detailed painting of a car. Usually, small parts like mirrors, handles, disks, moldings are covered with it, or damaged areas are tinted, and temporarily, since in this way it is not possible to protect the metal from corrosion without applying a primer. Moreover, it should be noted that although paints are considered to be intended for metal, the primer provides the best adhesion between the material and the coating.
As for chrome spray paint, it is considered a simplified analogue of real chrome plating. This is due to the following features of this material:
- First, the paint creates only an effect, the similarity of which with chromium may be distant, depending on the specific model of the substance. Some users note that the paintwork material in question looks more like silver than chrome, but at the same time it has a much higher cost.
- Secondly, in any case, this coating does not last long, acquiring a dirty shade over time. Therefore, chrome paint is usually used in pre-sale preparation or for touching up damaged chrome parts.
Some formulations in cans are labeled as acrylic. It must be understood that acrylic materials require mixing with an activator before use. And given the impossibility of finding these components in a cylinder in an unmixed state, such a name is an advertising ploy.
Before applying the paintwork material, it is necessary to prepare the work surface. First of all, the part should be dismantled from the car. You can leave it and cover all adjacent surfaces, however, given that small elements such as wheels, moldings, bumpers, mirrors are usually covered with chrome paint, they are usually removed. Next, the part must be washed using car shampoo, removing all contaminants. Then evaluate the integrity of the surface being prepared for painting. If there are defects, they must be corrected. Scratches are puttied and, after drying, they are cleaned with sandpaper, and corrosion is removed by grinding. The final stage of preparation is degreasing.
After that, a primer is applied to the working surface in three layers with breaks to dry each of them in 4-6 minutes. To speed up this process, you can blow the surface with a hairdryer. And the second layer before applying the third is treated with fine-grained sandpaper.
Before starting to apply the paintwork material, the can must be shaken several times to give the paint a uniform structure. Spraying is carried out from a distance of 25 - 30 cm from the working surface. For chrome paints, it is recommended to first apply a black substrate and polish it. Usually two coats of paint are applied, as in this way intense color and gloss are obtained. The latter is especially true for materials imitating chromium. It takes 15-20 minutes for each of them to dry, and the complete drying of the coating takes about 3 hours at a temperature not lower than 20°C. Then the surface is polished and varnished.
Failure to comply with the painting technology or the use of unsuitable materials can lead to the coating defects discussed below.
Peeling of the paintwork material a few days after painting indicates poor cleaning of the surface or poor-quality primer. The quality of the paint in this situation does not matter. The only way to eliminate these defects is to repaint.
The rapid fading of the paintwork material or a change in shade indicate an illiterately chosen putty.
This problem can also be solved only by reworking the work. That is, you will have to not only repaint the part, but also apply another putty. Uneven application of paint material on the work surface can be caused by excessive spray pressure or too high paint viscosity. This is usually due to its wrong choice, since such features are characteristic of materials that are not intended for painting a car.
