"When car headlights age and turn yellow, just spray them and renovate them." A product called "Car Light Repair Fluid" sells very well on the Internet. After using it, the evaluation of netizens is still very different. Some netizens who have successfully repaired it think it is an "artifact." ", while some complained that the headlights were destroyed after use, and some friends thought it was too difficult to do it by themselves. So does this kind of headlight repair fluid work? This article "MythBusters" will tell you through actual use. How effective is our car light repair fluid?
Car headlight shades are mostly made of plastic, which will cause some aging over time. The first reason why car lampshades are made of plastic is that they are lighter than glass and have a certain degree of elasticity, so they will not break easily in the face of slight impact. The plastic material currently used in automobile lampshades has high transparency and relatively low thermal conductivity. In addition, plastic has strong plasticity and is easy to process and shape.
Since car lampshades are made of plastic, no matter how strong the chemical ingredients are added within the controllable cost range, it is difficult to ensure that they remain as new all year round. As one of the most important external components of a car, aging is inevitable due to exposure to wind and sun all year round. So how should we deal with aging phenomena such as yellowing, scratches, and blurring of car lampshades after long-term use?
I believe the first impression of many friends is to replace a lampshade. However, friends who have changed headlights should know that the headlight assembly and lampshade of many vehicles are integrated. The lampshade cannot be replaced separately. If it is broken, it must be replaced together with the headlight. , the cost of replacement is much more expensive than the lampshade itself. Take the 2008 Qiyun car we restored this time. The cost of two headlights is about 500 yuan, not counting labor costs. If the repair fluid can successfully repair it, it will only cost a few dozen yuan.
Searching for "car light repair fluid" in e-commerce will pop up hundreds of links to online stores, and the brands are also very rich. We found a company that sells more than 700 pieces per month and has a total of more than 6,000 reviews. Let’s see what netizens say about car light repair fluid. Some netizens who successfully repaired it thought it was an "artifact", while others complained that the headlights were destroyed after use. I believe that many friends who have read the reviews are even more confused as to whether the headlight repair fluid is effective or not!

There is also a certain chance that the repair will fail due to insufficient operation. Everyone should make a rational choice when using car light repair agents based on their own circumstances.

The working environment of the car light repair agent is around 25 degrees. The temperature should be avoided to be too low or too high (below 20 degrees or above 35 degrees), otherwise it may cause liquid dripping, bubbles and orange peel shape on the surface of the layer.
If the headlight repair agent is accidentally sprayed on the car or windshield, you can use water or alcohol to wipe it off before it solidifies. If it is dry and solid, the glass can be gently scraped off with a knife, and the car paint surface can be polished.
If the first spray repair effect of the headlights is not satisfactory, and there are problems such as dripping or orange peel on the surface, wait for the repair agent to dry and then polish it again to repair it.
