Just wanted to chime in with my quick review. New black cadillac, needed to remove some swirls with m205. Then moved on to Carpro Essense. Essense was a breeze to remove by the way. A lot of nightmare stories about streaks etc.. but i found none of that. I believe a lot of these can be the result of leaving previous materials on. Thoroughly wiped off m205 with IPA.
On to the Blackfire Si02. Incredibly easy to remove. Perhaps the prep with essense helped but I did no IPA wipe down between essense and Blackfire Si02 and it removed incredibly easy. It got to the point i tried to make it streak by doing 2 panels and still couldnt. Its only been a few days so I will wait to see how it holds up with Florida weather. Definitely a fan so far
