Not sure how well a decal would hold up long term down low like that on a daily driver. The bottom of my truck had several spots where the paint was chipped from stones and such so before it began rusting I masked off the bottom 4 or 5" and sanded it down and sprayed Monstaliner with a shutz gun. They have many different colors and I found a red that matched my truck pretty dang close. My Ranch hand bumper and my fiberglass cap are starting to show some wear for the worse and I'm thinking I'm going to spray both of those as well.
