While wear is common enough that isn't something I have come across as the brackets seem to keep clear, have a good look outside to make sure no rubbish is fouling things and check that the mounts aren't distorted or loose........ I would make sure I gave each section a tug as I closed up so it didn't get scrunched so the area near the mounts should be well clear...
Has a strut come away from the knuckle joint at any time ??
Place a band aid over the marks on the outside of the screen, paint the band aid with crayon or string line chalk, close the roof as normal then lift up and see where its marked. I prefer crayon as chalk can spread.
