After reading about the famous Front Lip made from a Garage Door Bottom I said this is to cheap and to easy not to do it so I just finished it and I can't be happier with the way it turned out, definitely worth the 1.5hours and around $20 I put in it.
I used 3M black double sided tape and some binder clips to temporary hold it in place until it sticks. If needed I'll put some plastic screws in it.
Thanks guys for the great DIY ideas and sharing them with the rest of us.
I did a lot of them on my car (painted side skirts, painted stock wheels for winter, de-badged trunk, aluminum skid plate, etc.)
Let me know what do you guys think, here's the pics:
