TBH I have no idea what I'm doing with wax. I've always had a difficult time with it, this car in particular.
Think I was using macguiar's liquid wax.

When I was younger I remember using turtle wax which dried to a light haze. Easy to see, easy to buff out with a rag.
With this stuff, its state never seemed to change, and as such, every step felt completely arbitrary.

And now unfortunately, I have a bunch of what look like dirt swirls that I can't scrub out.
