What are the disadvantages of car waxing?

Disadvantages of car waxing: 1. Poor oxidation resistance. Basically, a single wax application can only effectively protect the car paint for 15 to 30 days; 2. Not water-resistant. When encountering rain or car washing, the car wax becomes ineffective; 3. Not heat-resistant. In summer, the car wax may melt and stick to dust in the air, damaging the car paint. Benefits of car waxing: 1. It can reduce watermarks, dark spots, rust, and damage on the paint surface; 2. It has anti-aging effects, reducing UV damage to the paint surface and extending the paint's lifespan; 3. It has anti-static effects, reducing damage to the car paint caused by friction with dust, wool fabrics, synthetic fibers, etc., in the air.
The first downside of waxing, in my opinion, is that it's too costly and time-consuming. As an average car owner with a limited monthly income, spending hundreds on wax or professional waxing services feels like a waste. The effects of waxing don't last long—gone after one heavy rain or a few car washes—so I have to repeat the process frequently to keep my car from looking dull, which defeats the purpose of protection. If I do it myself without proper tools, the wax ends up uneven or misses spots, leaving the car looking patchy and unattractive. Worse yet, some new cars already have advanced coatings, making waxing redundant. Last month, I tried waxing my car and ended up with small, blotchy spots on the paint, which took me two days to clean up—hardly worth the effort. Investing all that time and energy seems pointless when professional maintenance or other protective measures would be more cost-effective in the long run.
From my experience, the biggest risk of car waxing is improper operation that can damage the paint. I enjoy studying vehicle maintenance and have waxed my car several times myself. Each time, I had to be extremely careful to avoid minor scratches. If I didn't pay enough attention and applied too much wax or used improper force, it could leave tiny marks or halos on the paint surface, making the car look even older. Over time, accumulated wax layers tend to attract dust and contaminants, making car washing more frequent and troublesome. If not removed promptly, hardened residues become even harder to clean. Another issue is the unstable effectiveness of waxing—it only provides short-term surface protection and cannot prevent deep oxidation or acid rain erosion. I've seen many cars lose their shine shortly after waxing, exposing underlying paint aging problems. In humid environments, if the wax layer doesn't dry thoroughly, it may fog up or peel off, turning maintenance into a thankless task.
