I emailed John and got an email back pretty quickly.
The only thing I’m not sure about are the straps across the paintwork which will cause scratching.
Anyone able to confirm this, more visible on dark colours obvs.
I’ve never really worried too much
The straps are quite soft elastic and they are reasonable tight so only touch at the areas in tension
I keep my Mog waxed and reasonably clean which all helps of course
If you have to put it on after a long journey and the car is mucky, I’d just give it a quick spray of Detailer and wipe off any dust or dirt with a large soft microfibre on the paint areas where the straps touch
