Just to update… I installed the Velcro strips yesterday (they’re the same size piece as the plate itself).
For anyone considering the same, rest assured that there’s no chance in hell that the plate is coming off in my lifetime. The adhesive on the back of the plate is very strong, plus the Velcro itself is a really powerful type.
I accidentally touched the edge of the adhesive of the strip to the plate whilst trying to align it and I had to pull it with a significant amount of force to get it off.
nice one, thanks for the update.
