[Psychotic Mouse]

I stripped my bumper off and clued 5 x Neodymiun (rate earth) magnets behind the bumper. (20mm Diameter 5mm thick)

I then glued 5 of those to a number plate bracket, stuck some soft rubber pads to them so that they don’t scratch the paintwork.

This way I can remove the plate whenever I want and just pop it back on.

If you do the above then the best is to mount magnets onto the Numberplate first. The line it up on the bumper using the magnets on the inside. Once level while the magnets are in place, then apply the clue to the ones in the bumper. If that makes sense.
