Klasse before Supernatural?

[Job38]

Took the opportunity of this lovely autumn weather to detail the CSi (again).

I read somewhere a while ago to apply a synthetic like Klasse before carnauba wax to improve longevity of finish.
Is this correct, Klasse seems to be unpopular these days?

Thanks for the reply.

I've done an experiment and used only Dodo Juice Supernatural on the bonnet and Klasse plus Supernatural on the roof.
I'll monitor any difference.

The ease off application is exactly the same - obviously adding the Klasse is an additional process I could do without!

My gut feeling is that there's no point in using the Klasse first.

(The pre-wax was Menzerna followed by Sonus SFX-3)
