What is the treatment method for a cracked plastic panel under the car?

Treatment methods for a cracked plastic panel under the car are: 1. Pull over and wait for a tow truck; 2. Drive to a nearby repair shop for maintenance. Methods to prevent damage from scraping the chassis: 1. Apply chassis armor, which can be sprayed on exposed areas such as the vehicle's chassis, wheels, fuel tank, lower side panels, and trunk, forming a firm and elastic protective layer after quick drying; 2. Install an engine guard plate under the chassis. The function of the chassis is to support and install the car engine and its various components and assemblies, forming the body shape, receiving the engine's power to make the car move and maintain normal driving.
The plastic panel under my car was cracked once when going over a speed bump. At the time, I checked the damage and it wasn't too serious—just some scratches and small cracks. First, I cleaned the damaged area with a wet cloth to ensure there was no dust or grease, then I bought some strong waterproof tape online and applied it. The tape cost just a few dollars, and after sticking it on, I tested it by driving at low speed—it worked well and didn't loosen for months. These plastic panels are usually underbody guards or engine guards, and if cracked, they can compromise protection, such as allowing stones to splash in and damage components or letting water in, which can cause rust. I recommend avoiding potholes when driving and checking if the guards are loose before parking. If a large piece is broken, it's best to replace it, with costs ranging from a few hundred to a thousand yuan. DIY fixes are simple and cost-effective, but they're only suitable for minor damage—if it's beyond your ability, it's safer to take it to a repair shop.
As a parent with children, I place great emphasis on car safety and would never ignore a cracked plastic underbody panel. First, I park the car and inspect the damaged area to see if it affects the panel's stability or exposes critical components, as loose fragments could pose a hazard while driving. Last time, I temporarily patched the crack using fiberglass cloth and resin adhesive—common household tools suffice, but remember to wear gloves and ensure proper ventilation. This quick fix buys time, saves money, and keeps family outings convenient. For major damage, seek professional repair immediately; don’t compromise safety to cut costs. Without the panel, the chassis is vulnerable to scrapes—repairs may cost 1,000–2,000 RMB, but family safety is priceless. I also teach my kids to avoid speeding over bumps and cultivate careful parking habits to minimize impacts. Prevention is key: fewer accidents mean greater peace of mind.
