Heinz - I have raised & lowered the hood a couple of times just to check out how it worked, but definitely did not misuse any of the fasteners. I noticed the passenger side was flapping during the drive and on arriving home realised the self tapper had pulled clear of the woodwork, and that the driver's side was also loose (or at least, not possible to tighten fully).
The Tenax still held the self tapper, but the screw was clear of the woodwork.
I was warned repeatedly when I took delivery about how easy it was to raise or lower with a stud still fastened causing damage and I have not yet done that. (Yet)
