Sorry for your loss. Moral of this adventure is to be more patient with the hydration procedure. Also - adding a little bit of rubbing alcohol to the soaking rag (4X4 medical gauze works well) can help with hydration if water + time doesn't lead to eventual softening. You may have to cover the softening rag/gauze with "Saran Wrap" to maintain hydration. Working in the shade is best. Treat bird droppings with care - they often contain grit/sand/dirt particles can wreak havoc on a car's finish. Best to wait until the dropping is softened to the point where it can be removed by a stream of water (high pressure sometimes required). The little bit of rubbing alcohol will not harm your clearcoat and paint, but will remove wax, so the area in question should be re-protected after dropping removal. And yes, I am a chemist, amateur ornithologist, and OCD afflicted car finish wack-O.Marconelly wrote:This was quite possibly the most hardcore bird poo I've seen in my life. It just wouldn't get wiped away no matter how much wet paper I tried using on it. I think I got a bit overzealous trying to clean it, and the result is a pretty ugly looking swirly marks on the hood with clear coat scratched pretty badly.
