If I store the Mog with hood up over winter (to prevent shrinkage) I leave the Tenax unfastened, just in case I want something off the parcel shelf and 'forget'
I’ve taken to doing the same *whenever* the car is parked with the hood up, even if only for a short period. This helps mitigate the risk of lowering the hood or opening the rear to access the parcel shelf but forgetting to release the Tenax first.
I’m also going to a put cable tie or some other tactile physical tell-tale on the internal handle that opens the rear access to the parcel shelf. Perhaps that will remind me not to pull it without releasing the Tenax first (again!!)
The other thing I’m going to experiment with is not attaching the Tenax at all for driving with the hood down, but securing them with a couple of my daughters’ hair bands around the Tenax “mushroom head” to the inside of the roof frame hinge (there is a conveniently placed dome head nut inside). It will be interesting to see if this set-up provides enough wind and weather proofing whilst driving.
