Yellow stain on paint

JGreenwood07

Just picked up my brilliant silver 370z 3 weeks ago. I havn't gotten a single chip or scratch on it yet. I'm washing my car today and come across a small, thin yellow/brownish streak on the hood maybe an inch or two long. It's slightly hard, so I gently wipe it off as I'm washing the car. I've gotten these several times before, but have caught them and just wiped them off with a damp cloth.

When the car was dry, I noticed there was a faint yellow stain that remained. Running my finger over it I could feel where the residue was, as if it had etched itself into the clearcoat already. I tried claying the area, but had no luck. After doing some research online I figure it's either tree pollen, or bee droppings.

This had to have happened within the last day or two at the most, and besides the commute to work, the car is totally garaged for the entire day so I'm having a really hard time believing it could have etched itself into the paint.

Any other suggestions on how to remove it? Thanks for the help.
