The only one I've tried is Final Polish. Someone had sent me a PM wanting me to try the Vitreo (for free), but never shipped it.
I'm almost out of FP, so I may order that and the Vitreo and see which one I like more. I have to tell you though, I've been real pleased with FP...it almost lasts too long! Kind of hard to convince a customer that they need their vehicle waxed again when it still beads like mad after 5 months.
You might want to get hold of Brian (NY Detailer) since he has been using the Car Polishes line for a lot longer than I have.
