Between 7 and 10 weeks, weekly washing.
Slickness, beading and look won't tank after the first wash like many other more hyped products. In my eyes, it suffers less after the first wash that many others. Beading remains strong for the first washes.
I think it is durable enough for a daily driver, and I would even dare to use in the winter if a reapplication could be possible.
NBHFan, what is the meaning of "it pooled" Sorry, not native speaker of Shakespeare's language....
I am also surprised about the "white residue" It is white dust, or white staining? I found that applied thick is as easy as thin, but it will dust a little (logical if you ask me)
Now, if you are coming from the 845, not even the most ardent Mother's fans will tell you that FX will give a fight to the IW in durability..... not going to happen. If you don't mind spending 15 minutes to throw another coat every 6-10 weeks, this is for you. As with many products, 2 coats 24 hrs apart work better than one coat. Better coverage and the mild cleaners won't remove all of the first coat.
Intercooled, give it a try. You won't be dissapointed.
Edit: Did I mention that no other product sparked more comments about the car look than FX? For my car, it is so shiny that it hides the flake, and I don't like it, but the majority of the rest disagreed :nixweiss
