A couple of years ago I painted the bed with Herculiner. Had some left over so I did the rockers up to the first shadow line (if that is what it is called) just above the bottom of the doors. I like it; looks good and now more rock chips or cleaning the tar off of my white truck. Rockers had some brown on them from rust before I did the Herculiner thing. Now brown is showing through the Herculiner. So if I can figure a way to get it in there I may try to spray some Penetrol behind the rockers before it rusts through.
Have been looking for replacement rocker panels on the web but haven't found them yet. Anyone know where to get them?
