We are familiar with Flitz metal polish, but when I saw a Flitz spray containing carnauba and fillers, and a claim of "super gloss" that will last 3 months, I picked up a spray bottle. I finally used some after looking at the container for the past year, and want to share my findings. I topped Collinite 845, which was doing a great job of sealing my one stage paint. I was pleased to find the Flitz speed wax to go on and come off (even) easier than NXT 2.0. And it left a smoother finish. Good reflective shine on my Sierra Gold (looks more like copper) color. I'll never be able to report on durability, though, since the car stays garaged, and only gets wet when I wash it. I recommend the product for use as a good substitute for NXT.
