Did so on my new car, the license plate attached to the front and back.
Before the glue or Velcro detaches, it tears me down rather the complete bumper!
As some here have complained about the adhesive force: The Velcro can of course easily peel off over the sides ...
In addition, you should wait 24 hours until the 100% bond strength as is - "Waterproof" is then also.
Super product, right price - Thank tesa!
