Thanks all, your responses have been very helpful with providing me options to research. For now, after a lot of you tube video comparisons (with a grain of salt at some) I am zeroing in on MOHS Evo. This video was helpful between my final two contenders :
Now researching the prep steps and wondering if Iron remover is a necessary step. My car is always garaged, doesn't get driven over 7-8K/Yr and apart from rock chips, doesn't have many micro scratches or swirls. I rinse less wash it a few times a year and follow that with wax so the surface is pretty shiny and clean..
I suspect that since my car is always garaged, any of these name brand ceramics will outlast my ownership of the vehicle.
Please continue to share your knowledge. Thanks!
