I think we would have seen issues by now if the coatings weren't flexible enough for their application. As noted above, a think 1-3 micron layer vs. a solid cube is a big difference.
Are coatings flexible?

Thank you Rasky for the explanation. Glad someone here has ran into that issue to give us insight.

Joseph (Jsmooth) and a few others on here have come across it too. Sounds like quite a few Tesla's have had the issue.

Ive had it happen on 4 straight black cars a few weeks ago
two lexus, a bmw, and a cadillac
I polished with a D300/orange combo and the finish was completely clear of defects, then we polished it out to damn near perfect. Two shots of eraser, then 2 layers of Finest. Put the IR lamp on it and BAM, water spots all over the heated section. Moved the IR lamp to a different section, and more spots appeared. I was blown away and lost a $1800 job because even though I did the 3 step correction, I couldn't charge for the condition of the paint in the end.
So, on the next few black cars, and every black/whatever color car comes in with water spots, we do a complete correction, then IR lamp the panel prior to proceeding with the rest of the car. Just a precaution, but it has saved me 3 more wasted efforts.

I too listened to the Podcast.
None of this makes sense to me.
If the water that left the minerals behind was applied while the paint was hot and theoretically "expanded"; why would the water spot magically disappear when the paint was cooled and theoretically "contracted".
Aren't water spots actually damage to the clear coat? So expansion and contraction should only make the spot microscopically larger or smaller.
I would be be interested to see a more detailed description of the scenario where paint was measured while hot and then cold, with the hot measurement being thicker than the cool measurement.
The Defelsko meters are accurate to +/- (1/10 of a mil +3%), but in my experience, even trying to measure the exact same spot often yields different numbers.
