When your entire car is swirled and scratched, you’re going to exhaust yourself (physically and emotionally) trying to even everything out by hand.
Dark paints always show the most swirls, so trying to correct this paint by hand is a never.

Clay Bar Treatment
A Clay Bar Treatment is the process of using a clay bar to remove containments from the surface of your car. Common containments that pollute and slowly destroy your vehicle include things like rail dust, brake dust, and industrial fallout. These pollutants can penetrate through paint, glass, and metal and settle on those components even after several car washes and polishing.
