First I want to say I LOVE my Model 3 performance. I have had it for a little over a year and have 45K miles. So I drive it everywhere!!! We recently took it in (other issues were resolved) to have the roof looked at because it looks like something was spilled on it like a streak or the UV coating didn't make it to the entire roof. It looks like about an 8 inch streak or patch that only goes over the drivers side and not consistent at that. It was like this from the beginning, but only when wet. The Tesla app did not let me upload photos so the friendly service guy didn't see what we are talking about. I have made another appointment just for this issue now. Is there a way to see if the UV coating is on the entire roof? Other than the color? Does anyone else have this problem or similar problem? I also want to know if I am being a little too picky about this. Since the warranty is about to go out on this, I wanted to make sure it is not defective plus see if there is anything they could do to make it look better. I think I would be ok if it was on the entire roof. At least it wouldn't look defective.
