My new (lightly-used) Accent got hit with its first bird poop today. I washed it off with water, but I have no idea how long it might have been there, and I think I left a little permanent dull spot. Hyundai's clear coat/paint is supposedly, shall we say, not all that thick , so I'm worried about using any kind of polish on it. Maybe just wash and wax the car thoroughly? Also, has anybody tried a product I saw online called Poop-Off for Cars?
