James,

the problem with that sort of adhesive is that to remove the front grill and wings, as you know quite common in servicing an Aero, the number plate has to be removed as the 2 of the bolts that have to be accessed are behind the number plate!
My plate is pressed alloy and pulling at it to free the velcro would bend it.
Hence my wish to use screws.

Here is the trial fit.
