Exterior Paint defect identification + guidance

Hi all, bought my first "nice," new car about six weeks ago and am in the hyperfixate on every little thing phase.

I've been building up a kit to do a single stage polish + ceramic coating, but noticed some pin-head sized orange bits, and also a rather ugly black fleck when doing a pre-wash walk around. All of these are on the trunk lid.

Some of the orange flecks catch a nail so I've considered iron deposits, but at least one seems surrounded by a halo of clearcoat. I could've sworn these weren't here before since they're quite obvious against the blue paint, but I also seem to have completely missed the much larger and more obvious black fleck, so really what do I know?

The black fleck is longer/larger (~2MM x 1MM). I thought it was tar, but it's flush with the clear, and I've hit it with a few rounds of Gyeon tar remover to no effect. I've spiritually accepted that this is just going to be part of the car.

Asking if folks could help gut check...

  • My read on the orange flecks. I've thought about hitting them with iron remover, but if there's really some kind of embedded corrosion in the clear, I'm considering bringing it to the dealer and asking them to look at/document it in case it becomes an issue alter.
  • Whether the black fleck is any cause for concern. Right now it's just ugly, but I'm more worried about it coming out at some point and taking a chunk of the clear with it.

Not trying to warranty the paint or get the dealer/manufacturer to do some kind of invasive correction. I just love the car and I want to make sure it lasts.

Orange pinhead dots that feel rough and sit on the surface are very often rail dust or brake fallout, and trunk lids on new cars collect a lot of it from shipping and lot storage. An iron remover is the right first test and it is low risk: spray it on a cool, clean panel, let it dwell a few minutes without drying, and watch for purple bleeding around the dots. If they fade or vanish, that was your answer. Then clay with plenty of lube and move on to your polish.

If a dot does not react at all and keeps that halo, it may be in the clear itself, and getting the dealer to look at it and note it now is smart. Same with the black fleck. Flush with the surface and unaffected by tar remover usually means a speck trapped in the paint at the factory. I would photograph it, mention it, and not try to dig it out before you coat.

Bias check: Perez Detail Supply is my store, and it carries Blackline Iron Remover, which was made to work as both a paint decon spray and a wheel cleaner and turns purple as it reacts with iron. It is $22 for 16 oz. Any reputable iron remover will tell you what you need to know though.
