Wow black really does clean up nice. Your car being only 3 probaly don't have much for swirls in it anyways did it?
I had posted the pictures of my claybar,polish and wax a few weeks ago but it simply doesn't look as good (black vs grey may have something to do with it or maybe because my car is 9 years old

)
It is time consuming but I do highly recommend an orbital polisher (not a big buffer ). I picked mine up for 25$ at Ct on sale. easily saves you an hour or more nd lotas of pain. Perfectly safe too. You still have to do some work by hand ariund edges and trim but so much easier taking the wax off.
A car that looks like that easily adds a few 100 onto a private sale. 1. It looks good and 2. It looks like its been babied.
