However, a difference in color may occur even when using the original paint, due to the fact that the paint on the car ages under the influence of sunlight, temperature changes, weather conditions, exposure to chemicals and changes its color. In addition, there are paint fading and discoloration due to the use of inappropriate paint care products.
Coloring «metallic» consists of two layers - the main paint «metallic» and colorless protective varnish. When painting, a clear varnish is applied to the still wet base paint. For such coatings, the risk of a difference in the color of the paint during the subsequent touch-up is especially great, since the different viscosity of the repair paint and the original paint will lead to a difference in colors.
Repair of stone impacts
It makes sense to regularly repair even the smallest damage to the paintwork to prevent corrosion.
For small chips and dents that only damage the top coat of paint and do not require metal-to-metal protection for repairs, a coat of new paint is usually sufficient.
Deep dents in which rust has already formed should be treated with a rust remover or remove rust with a sharp knife or screwdriver until bare metal shows. It is very important that even small traces of rust do not remain. You can use a rotating small wire brush clamped in a drill chuck to remove rust.
Cleaned areas must be dried and degreased with a special solvent.
Apply a primer to the prepared metal surface with a thin brush. It is not recommended to apply a primer from an aerosol can, it is better to spray a little primer into the cap of the can and dip the brush into this primer.
After the primer has dried, apply paint on it with a brush. Repair cans with paint already have a brush in the lid. If there is only an aerosol can with paint, then you need to collect a little paint in the cap from the balloon and dip the brush into the cap with paint. Apply a thin coat of paint each time you apply paint so that it does not drip. Then the paint must dry. Continue the process until the dent is filled with paint and the area to be painted is level with the surrounding surface.
