It looks really cool but I never understood how it perfectly coalesces with the object

When you put your finger on a freshly painted wall, you get the pain on your finger. But there is still paint left on the wall as well.
It’s because both your wall AND your finger can adhere to the paint.
For hydro dipping, they use a type of paint that
* Do not stick to water (don’t know if that even exist)
* Do not mix with water
* Is less dense than water
As a result, the paint float at the top of the water. As long as there isn’t too much movement in the water, the paint can sit on top of it without issue. It is also important to not that paint stick to itself (I know it sounds weird, but it basically mean that if you move some of the paint, the whole layer can move as well.)
Then, you take whatever you wanna paint and slowly dip it into the paint. The side of the paint that point outward now find a surface it can cling onto and does just that. Also, as you dip the object into the paint, when the paint stick to it, it also drag the remainder of the paint along. this allow the paint to perfectly coat the object.
Think of the layer of paint as a layer of silk instead. When you push down, you drag the whole piece of silk down. Since its wet, it’ll cling to your object. You’ll have imperfection of course, but it’s not bad.
I think the simplest explanation is paint is made from oils and oil floats on water. When you dip an item it the paint surface tension and the water and paint not wanting to mix cause the surface paint to stick to the item and as it goes under it “drags” the oils paints across the water and down the initial dip point. Painting the object. It might be easier to imagine the paint as a sheet of plastic wrap on top of a tub of water. Wherever you push down on the plastic the rest will follow. That’s basically the exact same thing but both are liquid but oil is hydrophobic.
