Here goes.
Dont take it to a car wash. Do it by hand.
I would wash it first, then clay bar it.
Next I would polish it. ( I use Meguiars Ultimate Polish)
Next i I would wax it. ( I use Maguiars NXT Tech Wax 2.0 Liquid.
I do this about twice a year. You will only have to clay bar it once.
I used to do it by hand, but now I use Porter Cable orbital buffer.
(I do not use any Turtle wax products)
There are a lot of great products being used by the guys on this forum and you will get other suggestions but I have great success doing it this way.
As for roof cleaner, I don't know mine is a Coupe. Keep that Black car clean, it looks great.
