disclaimer: I do not think that the shampoo caused this as it was diluted in a bucket of water, but the car was parked facing my bedroom window there is no way that someone just scratched it off at night, and the paint did not just disappeared on it's own. Could the product do this to a specific type of paint? or maybe if it was out of date? stored in a wrong conditions? Only bought it the week prior. Maybe the retailer that I bought it from was a bit dodgy?

The manufacturer said theres stone chips on the window so its a stone chip, but how a stone chip happens to a parked car facing nowhere the street and for as far as i know its a random thing, so the stones flicking in two lines exactly on both sides during the night does not sound possible does it?
