If so, how does it compare to WetPaint?

 

I'm sorry I have not so I can't compare the two.

EDIT: I looked it up so I can compare, I didn't recognize the number. Meguiar'sFinal Finish is a quick detailer and a good one. It would be similar to many spray on wipe off products on the market. You would use it to give a quicky dust removal or just a quick shine.

Wet Paint is thicker and is designed to clean, polish, remove oxidation, remove dirt, and seal the finish. You rub it completely into the finish then go back and remove it using terrycloth.

Let's put it like this: A few days ago you put a couple of coats of Wet Paint on your car and it looks killer. You go out today and it's got pollen and a bit of dust on it, crap! Now you break out the Meg's and a couple of microfiber towels, spritz it on and wipe it down gently until the Meg's disappears and your original shine is restored.

They are two different products intended for two different purposes.

Got to the Wet Paint website and look at the video at the bottom of the first page.
