Its been awhile since anyone posted about this, so I thought I'd relate a little story to the group. Two days ago I parked the car and went in for lunch. When I came out, the hood of my car had a nice big bird bomb impact on it with a couple of secondary splashes across the hood. We have a nasty species of bird here called Russian Blackbirds by the locals (great-tailed grackles), which seem to eat and drink nothing but hydrochloric acid. I always take the car to the hand wash on the following day, so I foolishly did nothing to remedy the insult until then. The dried matter came off very easily, but the owner of the wash brought me over to look at an angle to show me that the main impact zone and a couple of the secondaries had left a mark which had etched into the finish. Long story short, it took them about 15 minutes of various compounds and wet microfiber cloths to remove and restore the finish back to good as new. He gave me a tip, which I will pass along to the group. Always carry a bottle of seltzer water (unflavored) and a microfiber cloth in your car. As soon as you see the bird bomb, soak it down with the water and gently remove it with the cloth. If you get to it quickly enough, the acid in the poop won't leave an etch. If you don't see it until after it has dried for some time, then you are going to need some kind of compound and polish to remove it. Again, time is of the essence. If it etches too deeply, you may even need to have the panel refinished.
