Kiwami a.k.a Extreme Gloss Wax is viewed as the successor of King of Gloss. It's a hybrid wax like KOG with 3 months of durability. All variants of KOG are a blend of mineral wax and synthetic resin. We mentioned KOG because it's important to understand the difference between Kiwami and KOG. Base wax in Kiwami is different across different versions. Kiwami white is based on mineral wax like KOG. But the silver and black variants are based on carnauba wax. With Kiwami white, you will get very similar result as KOG. But with Kiwami silver and black you will get different look i.e. deep warm gloss.
The following video shows the 50-50 comparison after application of Kiwami on a swirled paint.
