Thank you, Graham, Dave W, et al.
So my method for 'hood up' should be rear first, but not the corner tennax studs, then windscreen, then tennax's at the rear corner.
For hood removal, release the Tannax's at the rear corner and then the rear end, and finally the windscreen.
Have I got that right? It seems to work OK that way, but I still seem to be stressing the hood/windscreen when I erect the hood with the rear fasteners in place
