The other day I was washing my GT and found that a spot where some bird droppings was had left a stain in the finish that I can't seem to get rid of. It's on the new front quarter panel installed a few weeks ago. I believe the paint had cured enough to prevent this. I washed it, clay barred it, applied some paint cleaner, and then waxed but it's still there. Any ideas on how to get rid of it?
