So I went to New York for the weekend and I was picked up early in the morning. I came back the next day and went to get into my car and low and behold there was bird cdra on my hood.. No big deal, I just wiped it off. I noticed a stain on the hood so I washed and waxed the car. It still didn't come out so I waxed the area again. The SBM paint looks great without a bird crap stain so I really want it out. The stain is still there. Any ideas?
