May I address a concern that I haven't seen addressed here.

To quote Elvis' last words on this earth. "Corn? I didn't eat any corn."
A birds diet is varied and can contain small sand grains, crunchy things etc. So smearing this stuff around on your car finish is probably not a good idea. Soak and dab it, remove it and then polish and protect. Most importantly, get it off ASAP. I am guessing bird poop as a low PH.

Bird excrement is one of the most damaging environmental pollutants as they relate to automobile paint as it comprises; Ammonia and urine as white crystals of uric acid (pH 3.0 - 4.5) a small organic compound, which is produced by the breakdown of protein during digestion, and is excreted by reptiles and birds. Uric acid is also the end product of nitrogen catabolism in birds Ammonia is a mixture of nitrogen gas and hydrogen gas; with moisture as a catalyst it becomes Ammonium Hydroxide, which is caustic.

Heat and water act as a catalyst (reactivity); a vehicle paint surface temperature of >90.oF creates a very aggressive reactivity of the Alkaline, Uric Acid and Ammonia. This will cause surface etching, so they should be removed without delay. At lower temperatures (> 40.oF or less) there’s no reactivity and therefore little or no etching.

Their main food source in summer is mostly insects and seeds, in the winter/ spring it’s berries, which are very acidic, and if left for any length of time the will cause the porous clear coat to occlude (a non-transparent ‘clouded’ area) or may cause etching (a depression in the paint or glass surfaces)

Birds use gravel to help digest their food, predatory birds (owls, hawks, etc hunt and kill mice and small animals, so ground light weight bone fragments, sand and grit are some of the major components, which can cause scratching.
