dude, please don't take what I'm about to say the wrong way cause I don't like to criticize anyone else's work & not looking to hate, I'm only telling you this as I would tell any one of my friends really & just looking to help, but those bumpers really should be removed for paint, especially with a 3 stage pearl that will get a thicker film build to begin with. if they paint it all assembled together like that there are several drawbacks & the only reason would be to cut costs.
first of all the seems & edges will not be wrapped with paint, instead the paint will just be up to the edge. this can lead to the edge lifting & peeling eventually, not to mention it will also make the paint work much more detectable & noticeable... the grille should be removed and the bumper parking sensors should also be removed from the bumpers which requires the bumpers to be removed, just painting over them with the bumper together will also give you crappy edges around the sensors & again chance of peeling in these spots in the future too, plus again make it much more detectable, plus added film thickness on the sensors is also a bad thing for sensitivity. painting them should be avoided. the tail light should be removed & even the rear door belt molding, all these things are the difference between a good undetectable job or not, both now & in the future.
also, the parting line at the lower bumpers where the paint ends & the lowered texture part begins, if they just tape it off the way they have, that too will be an area of less than good, that break line takes a lot of extra prep to look crisp & they should use a fine line tape at that edge like what is used to create graphics for a clean line, else it'll look off. if your picky you will see all these things & they could be avoided with a little more prep now, before it's painted. once it's done then it's too late. it may cost you a few hundred more to disassemble the 2 bumpers but again if your picky then well worth the extra effort, just trying to help bro... the difference between really good paint work & not so great lies at the edges of the painted panels, def pays to address these things if you can
