i just spent close to 280 on a pc and product and a few other little things. the stuff will last me years even doing 3 or 4 cars. (not wax). pick something you like and stick with it.
I read about them on another thread here, and IIRC it had a link to a 1Z site that listed them. Something like "High Gloss Polish" or words to that effect. They describe it on the site as being for "ceramic paint".
That bit about Menzerna needing perfect conditions is one reason why I'd rather recommend 1Z to beginners. Note that I'm absolutely not knocking that product line.
I need to try my newer Menzerna stuff sometime, but FWIW I did a side-by-side on the S8 between the old FPI and the old 1Z Pro MP (AFAIK they no longer sell that formulation) and I liked the 1Z *much* better. I know, that's a crappy comparo, using discontinued products and all, but it goes to show that 1Z stuff can compete with the best. I have a vehicle here that was finished with PO106FF and to my eyes the 1Z stuff looks at least as good...the PO106FF finish isn't bad or anything, but it's sure not better as best I can tell.
