Vehicle preparation (newbie)

Hello guys, I want to clean up my paint properly. I thought about growing and first cleaning of course. I’ve never waxed a car before and have no idea about it. Of course there are a thousand posts from which I can pick everything out but I just wanted to ask you specifically if you’re definitely hanging out.

It’s mostly about what is good for my paint, of course it’s great if the eye is pleased with it. Greeting Benjamin
