In the post-car market, many of the years-old claims of repairing cars are inaccurate and are mostly the result of misperceptions transmitted through the mouth of experience. Many of the owners of the vehicles are vulnerable to inherent error in the face of dents and minor bumps and make unreasonable maintenance choices, either by spending more money or leaving the vehicles with long-term hazards. The kunming zone is built on a real-employer landscape, which is not exaggerated or fabricated, and combines the reality of daily maintenance with a stock-taking of some of the major vehicles on the high-frequency foothold of the owner, correcting misperceptions in plain and comprehensible language and helping to rationalize them。
The most common area of error is a small dent in the car. Many judge vehicles to be good or bad, depending on their ability to travel, and small dents in their appearance are considered irrelevant as long as they are properly speeded and the brakes stabilize. In the short term, it is true that the subsurface dent does not affect mechanical structures and the safety of motor vehicles, but the body metal is a stress material and the shape changes caused by external forces do not disappear. Long-duration vehicular vibrations and seasonal cold-hot alternations will continue to release residual internal stress from metals, and small, previously invisible dents will slowly become larger and more visible。
At the same time, the lacquer at the dimpled position will continue to stretch and for a long period of time there will be micro-cleavages invisible to the naked eye. Dust, rain and cracks into the ground floor of the plate can slowly cause oxidation and rust, and the difficulty and cost of repair will multiply when the rusty drums are exposed. These problems are slow to develop and are difficult to detect at an early stage, and often become entrenched when they are discovered。
The second common area of error: as long as it is not painted, all dimples can be repaired. In a realistic maintenance scene, this is not true. If the dim position is dead metal, rigid folding, the metal structure has been irreversibly altered even if the paint is complete. The metal fibres in these positions have been crushed and broken, and the mere physical thrust cannot be restored, and the forced operation will only tear the surface paint and cause secondary damage。
There is a clear and applicable boundary for scratch-free repairs, only for flat, non-repeated, painted natural transformations, a common understanding of the maintenance industry and no exaggerated universal processes。
The third area of error: untraceable repair is less solid than gold. Many subconsciously believe that the body of the car will be stronger after a knock, a moisten, and a painting, but the logic is the opposite. Arsenal maintenance requires a rust-proof layer at the mill, filling the indentation position with greasy, which is a hard filling material, free of metal resilience and prone to cracks and drums under cold heat alternation。
The non-striped restoration of compliance is the restoration of the shape of the altered metal, which does not damage the plate structure, does not damage the stain-proof coating, and retains the overall resilience and stability of the metal. In long-term use, the endurance of unrecovered repairs is more stable。
The fourth error: the option recommended by the maintenance shop must be the most reasonable. There are a number of integrated maintenance door shop main gold-painting operations, which, on a profit-driven basis, are recommended for refurbishment regardless of damage. Programmes are not differentiated according to the condition of the vehicle, the type of damage, but are simply applied to fixed maintenance processes, which is the main reason for the unwarranted destruction of many original plant paints。
The owner needs to understand that the maintenance programme should match the level of damage rather than the doorman's profit。
Fifth error: there will be no change after rehabilitation. Any body correction has a reasonable scope and cannot be absolutely perfect. Specialized repairs can be made with no trace of the naked eye and fit the arc of the original car, but with extremely strong light and close and precise observations, there are minor differences, which are normal processes and are not a maintenance quality issue。
A rational view of the effects of maintenance and the rejection of idealistic and absolute expectations can avoid psychological dissipation。
The cost of day-to-day car maintenance can be saved by not stepping in the wrong zone. In the event of a car dent, first the paint, then the shape, and finally, the selection of the car, not blindly overhauled, will be taken care of。
Simple judgement logic avoids most maintenance packages. Kunming's zero-deepness continues to share the writing of a physical vehicle science programme, based on real maintenance scene output, without making up concepts, without making up fictional effects and allowing the owner to understand the true vehicle maintenance logic。
