I am not sure what Velcro will buy you. Since rule [28] specifically says not Velcro, I would not represent it to the inspectors as part of your primary attachment system. ie The other fasteners would have to fully support the bumpers to the requirement of the rules.

Watching week one videos, I saw a lot of poorly attached bumpers though.

We used Velcro one year to hold down the battery. It work really well, but is was a pain to change batteries. It took a pry bar to remove the battery.
