Reversable Bumpers Illegal?

[Dominick Ferone]

For 2014 I made our team made "reversible" bumpers. They weren't reversible in the sense of them being attached but more the blue one gets placed atop the red layer, and can be peeled off.

I had used a staple gun and attached duralock to the plywood on the top, bottom and sides of the bumper where it wasn't touching the chassis.
Attaching them to the blue side was a little more challenging, basically i used the staple gun again while having metal on the underside the the fabric, this caused the staples to go through the duralock and fabric then bend, afterwords i used a hammer to push down any staple backs that were sticking out, and made sure no one can get caught on the staples.

The design worked well, the only problem I could think of is duralock takes more force to peel apart.
