What is the repair method for plastic screw holes on a bumper?

First, open the hood and remove the screws and clips on the bumper of the hood. Use a 10cm wrench to remove the screws and clips at the edges of the bumper near the front wheels on both sides. Next, remove the clips at the bottom. Use a pointed screwdriver to pry up the center of the clips, then pull them out to remove. Some may also have screws, mostly Torx screws or screws requiring a 10cm wrench. Use the appropriate tools to remove them.
Encountered a situation where the plastic screw hole on the bumper was damaged, so I fixed it myself to save money. The method involves first cleaning around the screw hole, using alcohol swabs to remove dirt and grease. Then, take a plastic welding rod and a heat gun to slowly weld, melting and filling the hole. After cooling, sand it smooth. If the welding is secure, re-drill the hole for the screw to tighten. The key is to control the temperature to avoid overheating and deforming the plastic. After repair, test the firmness and regularly check the screw tightness to prevent re-cracking. The bumper is an important protective component of the car; if the hole is left unrepaired, the entire bumper can easily fall off, increasing the risk of accidents. I often use this method to patch holes with good results, and the tools can be bought online for just a few tens of dollars, making it economical and practical.
