I have some experience to share:
2007 Mercedes Benz B-class B200 using Exclusiv ceramic fluorite coating.
It is much older car than yours, but it still looks very good.
Coating warranty 10000km / 12 months.
Customer came back for free inspection after 10000km.
Daily driver beater car.
Still as good as Day 1.
Should last him another few healthy years.
For car wash soap, you cannot beat this.
A frd gave his 7 years old 5 series a simple wash and wipe give this amazing slick shine.
He never done car care before.
對於洗車皂,你不能打敗這個。
一個frd給了他的7歲5系列一個簡單的洗滌和擦拭給這個驚人的光滑光芒。
他從來沒有做過護理。
