~ i use zymol 'concours' on my cars ... at $175 a can it's expensive but a container last me about 4 years (a little goes a long way)... i have been using it for the last 8 years or so ...

great stuff that actually produces a deep shine along with fantastic longevity !!!



the product comes with a serial number for each can & corresponding certificate of authenticity... for whatever that's worth.

as for upkeep... i wax my cars every 3 months or so... and use the 'V07 - chem guys' enhancement detailer spray after every washing with micro-fiber towels... and clay once a year.
