the choice of car wax In addition to the function of car wax, the following factors should also be considered in the selection of car wax: 1. Vehicle driving environment The waxing cycle for vehicles is generally once every 3 months, but if there are more sandstorms, rain and snow or serious environmental pollution, waxing is required once every 1 ~ 2 months. The choice of car wax should be based on one's own needs, for example, ultraviolet-resistant car wax should be considered in areas with sufficient sunshine and seasons, while waterproof wax should be used in areas with heavy rain and snow. 2. Paint condition New car or newer paint can choose soft wax, polishing and waxing at the same time; Sand wax and crude wax can be used for paint surface with serious scratches. First grind and polish, then polish with wax polish. 3. Paint Color When using colored wax, attention should be paid to the consistency between the color of car wax and the color of car paint. ( 2 ) matters needing attention when waxing Don't wax the new car casually. There is already a layer of protective wax on the coating of the new car itself. Premature waxing will remove the original wax layer on the surface of the new car, causing unnecessary waste. In general, there is no need to wax new cars within five months after they are bought back. 2. To reasonably grasp the number of waxing Generally, vehicles parked in garages or vehicles driving on good roads are waxed every 3 ~ 4 months. Vehicles parked in the open air are best waxed every 2 ~ 3 months due to wind, sun and rain. 3. Clean the dirt and dust on the car body before waxing. When cleaning the vehicle body, do not blindly use detergent and soapy water, because some chemical components contained therein will erode the coating film, wax film and rubber parts of the vehicle body, making the vehicle body lose luster and causing aging of rubber parts. If there is no special washing water, clean the vehicle with clean water. 4. When waxing, the car body cannot overheat. As the temperature rises, the solvent volatilizes too fast, leaving wax marks on the car body that are difficult to wipe off, and also affecting the adhesion of the wax film on the paint surface, thus affecting the wax quality.
