Welcome to Nico
You'll see lots of disagreement how to wax. Hack most places can't agree what wax to use.
I am usually lazy and just do a quick detail on the car. But if you want a really good detailing job you have to take a time and the tools to do that.
It depends what kind of job you want to do. Is there any swirl marks, scratches, etc or just a regular waxing.
Make sure you using only soft microfiber cloth anything else will make it worst than you start with.
There is a detailing forum on Nico.

It probably has lots of good info. Just please don't listen some of the youtube videos and comments.
Also Autopia has some good info if I remember right.
