If a vehicle is not waxed for a long time, its paint will lose multiple protective functions, leading to accelerated aging of the paint surface and increased difficulty in daily maintenance. The protective film formed by car wax can reduce water droplet adhesion by 90%, preventing paint oxidation and rusting of metal parts caused by acid rain penetration. Unwaxed car bodies are more likely to retain water stains and form stubborn limescale during the rainy season. High temperatures and ultraviolet rays can break the polymer chains of the paint surface, causing color fading and powdering of the clear coat, while the reflective properties of car wax can reduce ultraviolet damage by more than 50%. Unwaxed vehicles exposed to long-term sun exposure may develop noticeable color differences within three years. Static electricity generated during driving increases dust adsorption by 2-3 times, especially in dry seasons when unwaxed car bodies are more prone to accumulating dust and bug residue. Micro-scratches on the paint surface will gradually expand without being filled by a wax layer and may develop into visible swirl marks within two years. It is recommended to use synthetic wax containing polysiloxane for maintenance every 3-4 months, as such products can maintain longer-lasting protective effects. The interval can be shortened to once every 2 months during the rainy season. The cost of each waxing is about 30-50 Malaysian Ringgit, which is more economical compared to the 3000-8000 Malaysian Ringgit cost of paint surface repair. It is worth noting that vehicles parked outdoors for extended periods should also use a car cover to compensate for the protective limitations of the wax layer in extreme weather.
