My findings on this are that there's only so much that can be done to paint like this. My Granite '15 has some great spots and then there's the waviest damn sides on the doors ever. And just just typical orange peel like the paint was shot too dry, we're talking actual ripples and waves, ones that are very close together. They are perpendicular to the road surface, and extremely visible at certain angles of light. But as most have said here, wetsanding a factory paint job just isn't worth the time, or the risk, in most cases. So my regiment has been tailored to mostly hide the imperfections instead. It isn't ideal and the OCD in me knows what is under the paint, but at least it looks pretty good.
I've had the car only a few months, so I've so far done this to minimize the issues:
Clay resurface mitt (I use the Chemical Guys one but there are plenty good ones out there) with some lubricant and car soap in the bucket
CG P40 final polish on a white Hex Logic pad (I've not polished deeper than P40, haven't seen any scratches or swirls that exceed its ability yet on this new paint)
(the hiding part)
CG Blacklight on a white or blue pad
CG Glossworkz Glaze on a blue or black pad
Finish with Jet Seal 109 (could easily be Zaino, or a coating product)
This is very "multi-steppy" so I don't plan on doing it all the time, but the Blacklight followed with Glossworkz can really fill in a lot of the paint's imperfections. It can in no way remove them but can distract with a nice deep gloss and thanks to the Blacklight, a heckuva metal flake pop which really looks great.
If I knew I wouldn't burn through the clear in any circumstance, I'd happily take on the wetsand process, one panel at a time for weeks at a time, but you just can't guarantee that without knowing the paint's true depth.
edit: Still love the truck and the paint is still better than the Ford it replaced.
