I have a 2001 D2 with a Safari gard bumper and sliders. They are all getting little spots of surface rust and I'm trying to figure out what to with them. I was thinking of taking them off, grinding down any little spots and using POR15 to stop the rust. After that is done, I'm contemplating using a bed liner like LINE X or rhino line. As any one used this for their bumpers and such? I'm curious how it would look as a finished product and how it will last. Any pics from you guys would be great.
