I drive the wife to distraction cleaning my Zed, I have a polisher, only used it once on my previous Z4 not brave enough on this one as it's less than 12 months old. Mine is Estoril, I love the way it looks different colours depending on the light.
Thanks guys Estoril is a kinda polishers dream and does give satisfying results especially after having silver cars for years which only really shines in low light conditions
