Ding or METAL Defect From Factory?

[youtalking2me]

Was washing my car and noticed something on my passenger side front door.
A door ding would make a dimple, a small dent from the impact.
The thing I found, it seems as though the metal is bowing outwards and I can't for the life of me figure out what could cause that.
Its like a lump or a little mole. Im not sure how a impact, any type of impact, can cause a lump.
Anybody have any guesses? Want to get to the bottom of this.

Looks like debris that was trapped under the paint when spraying.

I have a similar lump on the rear quarter panel where it goes horizontal jut behind the small side window. I didn’t complain to the service center about it as it’s only visible when the light is just right.
