WD 40
One has to take a fine layer of paint little more deeper, evenly around the scratch, to remove scratches. In reality a thin layer of film is removed. Coating thickness has a lot to with the performance so it is not good to remove a good chunk of the coating layer in this process.
A dry film thickness gage come handy here. Check the initial paint thickness as one buff off the clear coat. Clear coats are ~2mils in thickness. If one is taking more than 2 mils, then clear coat protection is removed from the paint and we went into the base coat. As you know base coat has no exterior durability and will sooner or later result in coatings failure.
One option is to fill the scratch and wet sand it and repeat the process till it looks good. In many cases repainting is the best option.
There are so many fake videos out there to fool people.
WD 40 can only clean the surface of the paint, it cannot melt and flow the clear coat of a car.
People get fooled by this....
