Had a rainy day yesterday and I noticed the raindrops on certain parts of the roof looked different than others. Upon closer inspection, it turns out that I have 6 squares of "different" raindrops on the roof that are in a symmetrical shape and can't be washed out. I've already tried wiping it down with a soft rag from inside, then outside, issue persists.

My theory is these squares are a coating that should have been applied to the entirety of the glass roof, but somehow is only applied in these strange squares.

I'll post some pictures below, with rain, and without. Does anyone else have this on their Model 3, or should I contact Tesla about this?

With rain, harder to see in pictures, but noticeable in real life:

I would expect it is residue from the robot with glass suction cup hands. Try stripping the glass (or at least cleaning it) and see if you notice any difference.
