Consider that whatever condition your finish is in, you're going to be "locking in" that quality of finish for a long time.
I'm sure due to the cost of the coating, and all the other products, and work you're placing into the vehicle, you aren't going to be wishing to remove this coating 3-4 months from now due to a dislike of the quality of finish.
Even if not for any swirling, sleeks, one might wish to polish to just amp the gloss as much as possible.
Possible as well that the prep such as claying might cause some slight sleeks in the finish.
Yep, I know well, this is where all the hard work is, the prep prior to coating. The coating is the easy part IMO.
