My new (lightly-used) Highlander got hit with its first bird poop today. I washed it off with water, but I had no idea how long it might have been there, and I think I left a little permanent dull spot. If Toyota's clear coat/paint is thin (I don't know that for a fact), I'm worried about using any kind of polish on it. Maybe just wash and wax the car thoroughly?

Also, has anybody tried a liquid product called Poop-Off? I see it advertised a lot on the Web.
