Then here is what you must have a thorough understanding of. You have ROCKS sitting on your paint. They may be the tiniest rocks that you have ever seen in your life but they are still rocks. If you MOVE any of those rocks against your paint, you be creating what is known as SANDPAPER. It may be 5000-grit sandpaper but it is still sandpaper.
If you grind any of those rocks against your paint, YOU WILL SCRATCH THE PAINT. This damage may not be instant to the eyes, where you can immediately see it on a light colored car but on a dark colored car, the damage will show immediately. That is, if your paint is TRUELY flawless. So what you have to do in order to avoid this damage is to figure out a way to remove those rocks
without grinding them against the surface of the paint.
You have THREE choices. You can do a proper 2-bucket wash, which is the safest thing to do when dealing with flawless paint. Two, you can take an electric or battery powered leaf blower and blow off what dust can be removed that way. It may not leave the car looking perfect, but it will appease you to some degree. Last of all, you can do what I do.
Leave it alone until you can do a proper 2-bucket wash. The dust is NOT hurting anything or creating any damage
as long as you do not disturb it. By taking ANY product, I don't care what it is or who makes it, spraying it on your car and then wiping a towel against the surface of your paint, you are GRINDING those rocks into your finish.
You have just successfully made SANDPAPER. It will do what sandpaper does. You repeat this process over and over again and your paint will look like trash in no time. To folks who are as anal as I am about flawless paint, we can see that damage immediately.
There are people who have dark colored cars who do this practice. When I ask them about their finish, they tell me that it is flawless. I ask them to see their car. This is what they, and other individuals with untrained eyes see:
But to someone with a trained eye, this is what I see (click the picture):
Even though the damage is as clear as day to me, I do something that makes it MUCH easier for someone with untrained eyes to see all that damage. I call it "the flash test". I shoot the flash of my camera off into their paint. This is what I reveal to them:
That damage is created by constantly wiping DUST off of your car. I knew his paint would look like that when he asked me the same exact question you are asking, but the only reason he asked me for something is because he could no longer find what he was using. I immediately knew his paint would be jacked up because no one who knows better is going to remove dust from their finish in that manner.
By the way, I did a quick fix for him, just one pass with a compound and showed him the difference:
So if I were you and I REALLY had flawless paint,
I would follow the ritual that I follow. Or, I would do the other thing that I do right after I wash the car and ONLY right after I wash the car, I would cover it. But even the way I cover my car is a process because covering your at the wrong time, the wrong way and using a crappy cover is ANOTHER way to make sandpaper. Avoid sandpaper unless you are wet sanding.
Don't fall for the hype. There's a ton of it out there and manufacturers want you to believe what they say and NOT what they can't show you. If you cannot not show me the science behind HOW your product works then you are asking me to believe your claims. Not happening in my world because I can prove beyond a shadow of a doubt that ANYTHING I claim will work, guaranteed. If I can do that, every manufacturer who sell detailing products should be able to do the exact same thing. Reason? Because I don't detail cars for a living nor am I in the detailing business. The manufacturers are, so they should be able to do exactly what I can do. Prove what I say is gospel. 😉
