what kinda car does your dad have?
He has an 2002 S80 T6, Nautic Blue. The Father Son Combo.

i am planning on taking superglue and applying it to some double side tape and the foamy piece. That will keep the tape and piece together. The other side of the tape with no superglue will go on the bumper.
Good luck with that, I have a feeling it may start peeling off unless you use the like 10lb double sided tape, then load it up with glue, I have a feeling if you ever scrape on a curb or speed bump it might tear right off, and I know mine hasn't going over some pretty big snow chunks.
