Black paint is notoriously hard to keep clean. While it looks great new, it shows every spec of dirt, dust, scratch, or imperfection. Even when lovingly cared for, making a black car look show quality is a challenge. When neglected, well, you might as well keep it covered in grime.
Looking at this 2017 Nissan Sentra Nismo, The Detail Geek has his work cut out for him. Barely six years old, the paint is heavily damaged with swirl marks making the car look much older. Unlike the Mercedes AMG GT with a ceramic coating, it's doubtful the car has ever been waxed except at the automatic car wash.
