I cropped out just the part that matters...
Looks like someone rubbed something abrasive like a compound over a spot of some type. Now you have the spot plus scratches.
Take a white polish and a white cloth and rub lightly on the spot. If you pull the color of the paint the clear coat is missing.
If you don't pull the color of the paint then what you're experiencing is a phenomena characteristic to modern clear coat paints and that is they are hard.
Hard in relationship to the only other paint system we've had in the known history of mankind and the automobile, which is single stage.
This is why so many people have switched to machine polishing because they have discovered how difficult it is to fix paint defect by hand due to the hardness of the paint.
I cover ALL of this in my how-to book.
Paperback
So do some testing and tell us if you're seeing colored paint on your testing cloth.

Yes.
I'm making a video on how to hand apply UC Thursday night on this car. There is more technique to working by hand than by machine.

I perfected this technique and have taught it to a LOT of people over the years and want to share it via video at this point in time.

I don't think it is from the pictures. It just looks like something that needs to be compounded/polished out :xyxthumbs:

That page you referenced has a link to two cars I buffed out and were used on Meguiar's bottles. Technically I only sanded and buffed the black car which is a BMW and I led a team of guys to do the extreme makeover on the Mercedes-Benz, these two cars..
They actually toned down the swirls for the above picture, here's what it really looked like...

I don't think it is either but the test I told him to try will let him now real fast. If it is just scratches and a round stain spot then he can probably remove the scratches and maybe the stain spot.

Yeah, I have already advised your tip to see if clear coat is there or not to several people in person... it's a good test :xyxthumbs:

When you rub the Ultimate Compound over the affected area using a white cloth of some time...
Do you see the olive green or brown color of the basecoat, (that's the colored layer of a basecoat/clearcoat paint system), transferring onto the cloth?
If so that means the clear layer is missing in this area.
If not, that means the spot is some type of stain or imprint and "possibly" you might be able to remove it by rubbing the area with the Ultimate Compound.
At a minimum you should be able to remove what looks like scratches surrounding the spot.
Some defects cannot be "safely" removed due to the thinness of the paint.

What you want to do is basically what I show in this how-to article only you're not testing for a single stage paint job you're testing to see if there is missing clear coat.
The test will tell you. If you're working on an intact clear coat finish you should not see any color or pigment coming off the area you rub with the Ultimate Compound.
How to Test for Single Stage or Clear Coat Paint
To test for a single stage paint, try to find a light colored or white polish if you're working on any kind of pigmented paint. If you're testing white paint then try to use a polish with a color to it and a dark colored cloth, (so you can confirm that you're removing white paint and not just seeing the color of the paint).
Use an ample amount for plenty of lubrication as you're going to want to push firmly if no oxidation is present as was the case with the finish on the classic car.
Confirmed, we're working on a single stage paint... also note the heavier accumulation were my fingers pressed down with the most pressure... this is because you can exert more pressure to the small area of your finger tips than you can with your entire hand, you can use this to work for you or cause problems depending upon what you're trying to do...
