This is a little more infuriating than “mildly infuriating” but I can’t think of a better place to post it
Edit: I’d like to clarify that I live in East Tennessee, not an area like Florida! I do appreciate the hints that it might be clearcoat goblins though, and I’ve left a saucer of milk and cheese out to ward them away
Not necessarily a stone chip, but likely a tree branch chip that started it! This is the rear wing on my car so I feel like a stone hitting it is a little unlikely, but ultimately not impossible I suppose. The spot wasn’t growing at all when I originally noticed it, then one day it was massive. I always took care around it because I obviously didn’t want to make it worse by washing it.
I suppose it’s possible that the horrendous rain around here did it though!
I’d just touch it up with some repair clear coat if I were you
For real, they make like a $30 can of 2K clear coat that has a little button in the bottom. Watch some YouTube videos on how to apply it, tape off or mask off everything around it, respray and you’re done.
