Door runner - paint finish

[GraemeP]

I’ve noticed on the rear quarter panel where my door slides into (half way up), the panel feels a bit bumpy, and when I look in or put my finger in the recess, I can feel where paint finishes and bare metal exists. Doesn’t look like it’s been damaged, but doesn’t feel like a good finish. I’ll go check my friends later - anyone else notice this or is mine a Friday afternoon finish??
