Rear Cab Pillar Scratches; Airflow?

[Chevyspeedster]

Anyone else having these strange scratches show up behind their cab?

They’re on both sides. I’m thinking it may be from airflow from normal driving. I haven’t been on a highway too much so not ‘high speeds.’

Nope none on mine. I just got done waxing it. Is that damage on the front of the box also or a reflection?

Roll up soft tonneau cover with the straps to hold it rolled up? Need more info on what you've got going on in the bed. Scratches don't just happen from air. Something has to hit it or rub on it.
