shouldn't put wax on paint less than 6 mo old. It needs to breath.
I used a 10" orbital polisher:
1st step: Sealer & Glaze (Terryclotch) (1 hour)
2nd step: Pure carnauba wax (Terryclotch) (1 hour)
3rd step: Polishing the car with sheepskin bonnet (15 min)

Both products from Mothers, very expensive stuff, but perfect result.

I didn't use a paint cleaner as my paint is brand new.

Now, I can see myself in the car.
