I've been using Zymol Japon for some time and it is fantastic. It is supposedly formulated for Japanese paint. Best shine I've ever gotten, including Meguire's and Mothers. And for those with Ebony cars or '92's with black upper bodies, Zymol Carbon Black colored wax cannot be beat! Makes all those hairline scratches disappear. It's bl***y expensive, though, at $50 a tin...
