What are these spots on my car hood?

[joe6666]

I found three gray spots on my hood.
Tried soap, wax, 92% alcohol, and fingernails, and none removes them. Their surface texture feels smooth, but not as slippery as the clear coat.
Any idea how to remove them?

Questions for you....

Is your car garaged or sit outdoor prior to this?

Did you Park in a indoor parking Lot?

Did you recently drove under an overpass or a bridge under construction or road maintenance?

How long has it sat on the paint?

some type of etching- probably going to have to use a polish- try by hand first, but might have to break out the polisher

Agreed if doesn’t feel raised some thing etched into paint. As stated above i would try hand polishing with different levels of abrasive polishes. StRt with least aggressive you have

Agree on the etching. To me they look like a bird dropping(s) that wasn't washed off in time and etched the clear coat.

Without knowing all of the contributing factors, I am going to say bird droppings and etching from that. Cut or polish them out.

I'll disagree with all of the "etching" comments... If you look at the close up pics (especially #2) it appears that there is some type of material bonded to the surface. It appears "proud" of the surface, not "recessed" as would be the case with etching.

Exactly what the material is? I have no idea.

Some type of careful scraping/abrading action followed by a localized polishing would be my thought on how to remove, but only and after I exhausted some less aggressive attempts like solvent, polish, etc.

Were you parked under a tree? Tree sap maybe?

The car had been parked outside for an year since it's new, and it has been moved into a garage for 4 month until now.
I believe the spots are from times when the car was parked outside, and I would say it's about 10 months ago.

The are less likely from bird drops, since I cleaned bird drops if I see them, and the areas would be larger.

Do they feel raised as something on the paint, smooth or recessed(in the paint)?

If raised i would give a plastic razor blade a try. Their available on AG. Use alot of Lube.
