Meguiar's Gold Class is a blend of polymer and carnauba, with some cleaners added into the blend.
It provides a nice shine and has a very light cleaning ability to it, more of a step between a true cleaner wax (I believe Meguiar's cleaner/wax in burgundy/maroon bottle has a stronger cleaner in it) and a pure wax (has no cleaners in the wax, like Meguiars #26 or P21S.)
I have a can sitting at home. I don't use it much anymore. It doesn't last long but provides a good shine (clouds up certain german finishes in my experience (a 2000 silver BMW....)
If going Meguiar's I would go with #26, but why not add $5 more and get a can of S100 wax which gets rave reviews on this forum.
My P21S kit is on the way!!!!
