The Blackfire products blow Zanos away. Happy to box all my Zanos stuff up and ship it to someone else for a wooden nickel!
I'm telling you I have purchased every wax and high end sealer on the market. I have more detailing stuff than most detailers. I use the Wet Diamond all finish paint protection. It last about 3 months in Minnesota. When I really want to show off I top it with the Midnight Sun wax. All are very easy to use ( Zanos is a real pain). The Blackfire swirl products also really work on the very hard BMW clear coat.
You can cleck out my work on the "Triple Black" thread.
