👉 Automobile pimples, also known as wheel wells or underbody blemishes, are cosmetic imperfections that occur on the underside of a vehicle's body, particularly around the wheels and underbody. They typically manifest as small, dark circular or irregular spots caused by oxidation of the metal beneath the wheel or underbody paint, which can also result from dirt accumulation and rust. These spots are often exacerbated by exposure to the elements, such as moisture and UV rays, and can appear as a dull, brownish discoloration. While not harmful to the vehicle's functionality, automobile pimples can detract from its aesthetic appeal and are sometimes targeted by specialized paint treatments or underbody coatings to restore a more polished look.
