What if the headlight cover starts to turn yellow and no longer lets in light?
Headlight repair, refurbishment, polishing or coating?
This is a serious question....
Is it really possible to renovate and repair headlights?
Before we talk about this problem, let us first understand the structure of the headlight cover. Generally speaking, the headlight cover is divided into two layers, the inner layer is plastic and the outer layer is film.
High temperature, ultraviolet rays and ozone will accelerate the aging process. In addition, the car's daily use environment, if you often drive into areas with chemical leaks, or in industrial areas with dense pigment/dye production companies, or even use the wrong car cleaner / Maintenance supplies may cause the lampshade to turn yellow.
Nowadays, the headlight covers of most cars (the inner layer just mentioned) are plastic products made of polycarbonate (PC) or polymethyl methacrylate (PMMA) plastic injection molding. They will gradually age during use. The specific manifestations are as follows: Yellow, reduced intensity, etc.
High temperatures, UV rays and ozone all accelerate the aging process. In addition, if the car frequently travels to areas where some chemicals leak, or is in an industrial area where pigment/dye manufacturers are concentrated, or even uses car cleaning/maintenance products incorrectly, it may cause the lampshade to turn yellow.
Headlight repair is a cost-saving but effective method.
Use a degreaser cloth dipped in a little treatment agent to remove the oil and wax from the surface of the headlight! Then determine the type of sandpaper to use for polishing based on the depth of the scratch.
During the polishing process, depending on the degree of repair, the sandpaper must be replaced in time to avoid unnecessary scratches on the surface of the headlight!
Generally speaking, when a headlight turns yellow, it is the film that is damaged, mainly the plastic surface (yellowing, whitishness, cracks, small shallow scratches). In this case, the headlight mask can be repaired and refurbished.
Headlight repair can be said to be a low-cost method with good results.
The method is as follows, first use a small amount of treatment agent to clean the oil and wax on the surface of the headlight. Then determine the type of sandpaper based on the depth of the scratch.
The sandpaper must be replaced in time during the polishing process to avoid unnecessary scratches on the surface of the car lights.
After polishing, use an air gun to blow off the moisture and dust spots on the headlight. After it is completely dry, wipe it with a dust removal cloth, and then spray the headlight repair material, so that the headlight is repaired!
Of course, there are rumors that pesticides can also renovate headlights... (If you take it seriously, you are really stupid)
The last method is to buy a new lampshade and replace it. It is convenient, simple and quick, and you can also replace your candle lamp by the way. It kills two birds with one stone. This method is suitable for car lovers, why is it not considered a trick, because they all bought new cars...
After the polishing is completed, use an air gun to blow off the water and dust spots. After it is completely dry, wipe it with a dust removal cloth, and then spray the headlight repair material. In this way, the headlight repair is completed!
Safety reminder: Professional modification and upgrade of car lights is to not affect the driving safety of others and to ensure your own driving safety. You need to go to a professional modification store for lighting modification and upgrade!
