has anyone made a one off areo kit using foam, like the one in the pics below?
1. what is used the secure the foam to the bumper?
2. does the foam remain secured to the bumper as part of the finished product?
3. What makes this process secure that foam and fiberglass won't separate from the bumper and fly down the highway?
any tips from those who actually have done this and are experienced would be appreciated.
steps, instuctions, etc..
