I have an epsom green truck, metallic dark green. There was a small rust spot on the rear door sill, seems many rust out there, it looks like it is a single layer of steel, with the other side exposed to the elements. I drilled it out and filled with epoxy, primed and sanded it. I found repaintsupply.com for touch up paint, kit comes with a bottle of paint, primer and clear. even with my amateur skills you can barely find the repair, its about 1.5" square. I have not buffed it yet, but it looks fantastic. I thought I would share the source if people need paint.
