Holy $hit batman!
I couldn't help but notice this purple blob on my bonnet and by the time I got around to cleaning it (very difficult to get rid of) I left a mark on the paint. I think it was was bats dropping fruit unless their poo is purple. But whatever it was must have been highly acidic and very bad for paintwork. DOH! DOH! DOH!
bloody bats!
