Those look like clamp marks from the forming machine.

Yeah, probably how they got the continuous width piece of metal to "shrink"/bend in two directions at once, like corrugating it a bit?

Now I know what a striation is . I'm only guessing but I'd say it's for shrinking where there's a bend.

I have seen those shrinking marks on charger and front wheel well trim. However, not all trim had those marks.

Just teeth marks from the shrinker stretcher. Looks like someone got hungry in that spot.
