Topping Klasse SG with Collinite IW845?

[BigFly10]

Would there be any benefit to doing this or would I be wasting my time? Furthermore, would 845 potentially diminish the effectiveness of the SG? I tried searching for the answer to this but could not find any definitive conclusions.

Thanks in advance.

I just did it in April, AIO once SG 4 times and topped with 845. Probably overkill but 845 gives extra depth and I love the way it looks after the rain

I used AIO + SGx2 + Collinite IW x2 on my wife's Audi A4 this past winter... looked good, provided excellent durability, and only had to boost it with OCW in February to keep up the look and the slickness until the end of March.
