After I put my new motor in I noticed the paint on the fenders would bead water where I got oil on them. Even after several weeks and me trying my best to wash the oil off the fenders still beaded water. So I just oiled the whole truck and let it set a couple days. I didn't want to ride around on a greasy truck so I applied a couple coats of Johnson Paste Wax over the oil. Johnson Wax doesn't leave the white residue in the cracks like car wax.
It doesn't shine like a polished and buffed job but it brought the color out and still beads water like new paint after about six months.
