I bought a small amiunt of gear to clean the car as below..

Now I got all this stuff about a month ago, and the car still looks fresh, and rain beads up nicely but I feel like I want to polish it up again using the utoglym resin polish as in the picture, and then wax again.
The paint still feels smooth, and from what I've read I don't need to clay again.
So my question is,do I just go ahead and re polish and re wax, or do I need to use some kind of cleanser first?
