To me... that looks like fractured or cracked paint caused by a bird dropping etching.
Here's my article on this topic....
Two Types of Bird Dropping Etchings
Here's a portion from the article,
Type II Bird Dropping - Fractured/Wrinkled Etching
Type II Wrinkled Etchings are usually too deep to fix safely. The problem is the paint fractures, (splits apart in tiny lines,), or wrinkles as the paint swells and bunches together. In both instances, the resulting defect is throughout the clear layer of paint and not topical. Thus trying to remove it will require removing so much clear paint that you will likely expose the basecoat, or colored layer of paint which has a dull appearance. For this reason it's not safe to try to remove a Type II Bird Dropping Wrinkled or Fractured Etching.
The pictures you attached show what looks like cracks or fractures intheh paint like you see above.
These cracks run throughout the thickness of the paint. So compounding or even more aggressive, sanding on top of the cracks won't remove them it will just uncover more of the cracks.
Makes you wonder... what's inside bird droppings that they can be socorrosivee?
You have two simple options.
1: Learn to live with the defect.
2: Take you car to areputablee body shop and have the affected area repainted.
For the cost to have the panel repainted, somewhere between $300.00 to $1000.00 depending upon the caliber of the shop, plus the potential for related problems that come when you take your car to a body shop... it might be a better option to just learn to live with the defect.
Hate to be the bearer of bad news but that's my take according to your pictures.
Also, since this is your first post to AGO...
