Just a small question for the guys in the know. What's the chance of bird crap being so acidic it will eat into the paint and cause a frosted etched effect in less than 6 hours. Reason I ask is I spent the weekend detailing my car but when i came out of work this afternoon there appeared to be a dollop of bird crap down the passenger side. Must admit it looked a bit weird and more like a splat of mud. Anyway, washed it off this afternoon and where it was left what I can only describe as a frosted etched look to the paint. It eventually polished out out with some Merzerna after about an hour of going over it. I just can't believe its possible for bird crap to cause that mush damage in less than 6 hours!
