Wash bat droppings off your car immediately. Sometime recently a bat messed near my new car and five tiny spots got onto the bonnet. Well the detailer got most of it out yesterday, but a tiny spot of it had eaten through the clear coat put on the car when it was made in January. (The car was there getting some scuff marks removed, they were from when it was delivered and the car company paid to have them buffed out)
Anyway you have been warned…or did everyone know this except me…I knew eggs and brake fluid ruined your paint, but not bat yuck!
