If the hard plastic on the dashboard is damaged, you can first secure the broken plastic part and then use a welding gun with welding rods to perform high-temperature spraying, allowing it to fuse and cool. Below is an introduction to the dashboard: Introduction: The dashboard is the most complex interior component in a passenger vehicle. From design to installation, it must undergo processes such as creative styling, structural design, model making, and trial assembly of prototypes—each step is indispensable. For example, in terms of styling alone, the interior components of the roof can skip the styling design phase and proceed directly to model making, but the dashboard cannot: without a styling effect drawing, model making is impossible. Additionally, the dashboard involves various aspects such as ergonomics, material engineering, processing methods, and production workflows. Dashboard Classification: Based on installation position, dashboards can be divided into three types: main dashboard, center console, and overhead dashboard. The main dashboard houses the most indicator lights, gauges, and commonly used control buttons. To facilitate the driver's real-time monitoring of driving conditions, all operational indicators are placed on the main and overhead dashboards. Critical data that requires constant observation (such as speed, brake indicators, and fault displays) must be positioned on the main dashboard aligned with the driver's seat centerline. Furthermore, the main dashboard also features 2–3 air conditioning vents.

The plastic dashboard of my old car has a crack. I fixed it myself with AB glue, and the result is okay but not very aesthetically pleasing. First, thoroughly clean the surface with alcohol to remove grease and dust. Small scratches can be smoothed out with dashboard repair paste, but for larger cracks, you need to sand the edges before filling them with glue. There are dashboard-specific repair kits available online, some with color-matching cards to help match the color. Remember to work in a well-ventilated area and wear gloves. Plastic parts are most vulnerable to direct sunlight, so it's best to use a sunshade when parking in summer. After the repair, regularly spray some plastic protectant to slow down aging. Dark-colored plastics show less noticeable repair marks, but for light-colored cars, it's advisable to seek professional help.
