What is the method for repairing cracks in car light covers?

First, clean the headlight as thoroughly as possible with water and a damp cloth, removing any areas where stains have not yet become stubborn, which can reduce the workload later. Use six different grades of sandpaper, from coarse to fine, to sand the headlight. The purpose of this step is to completely remove all oxidation layers from the headlight. Use the atomizer in the refurbishment tool to thoroughly atomize the coating solution. Only proceed with coating the headlight when the steam emitted from the atomizer is continuous and uniform.
My car's headlight cover also cracked last year, and I tried repairing it myself with good results. First, clean the crack area with alcohol to ensure there's no oil or dust. Then apply professional UV repair adhesive, which can be bought online in small bottles for just a few dozen yuan. After application, use a UV lamp to irradiate for five to ten minutes to harden it, and finally lightly sand and polish with fine sandpaper to restore transparency. The whole process takes less than half an hour, saving hundreds of yuan on a new cover. Unrepaired cracks can easily let water in, damaging the bulb and affecting lighting brightness and driving safety. After repair, the light diffuses normally, making nighttime driving much more reassuring. Regular care to avoid the cover being hit by gravel can greatly reduce such minor troubles.
