Hmmm, maybe it has to do with the lighting conditions to see the smearing. When I wash and detail my car, it is in a enclosed parking garage with fluorescent lighting. My car is silver and after trying both Show Off and Clear Pearl (0n different occasions), when I remove it with a MF cloth and look at the roof of my car, at an angle that reflects the fluorescent lights really well, I can see smearing all over the place. By the way, when I pull the car out in the sun, you cannot notice the smearing like under the fluorescent lights. It is also difficult to see the smearing on the door panels, fenders, etc because the angle of the fluorescent light on the car. It requires some real buffing with a soft cotton cloth to minimize it. When I say real buffing, I mean, I could remove a coat of Blitz wax with less effort! However, when I use Meguiars FI, it easily wipes off and the shine in the fluorescent lighting is spotless. So after I wash my car, I'll stick to using FI or I might as well add a coat of Blitz instead of SO or CP, if major buffing is needed. As an additional note, my paint is in excellent condition, the car is only 3 months old, it has a coat of IHG/Blitz and I hand wash it weekly with Mothers Cal Gold car wash. I know, someone will tell me to change the fluorescent lights to incandescent and the problem will go away
