Many car buffs and sites recommend Zymol. I noticed that many on this site prefer Zaino over Zymol - so it must be good stuff. (It appears many VX owners on this site are a step ahead).

Collonite (sp ?) appears to be another one that many 'in the know' prefer. A few of my friends that are in the body shop business (or related) use 3M products and Collonite.
