I ordered a new body, the Proline '66 Ford F100 Lexan body.
I created a light surface rust look by sprinkling nutmeg on a coat of wet clear paint, once section at a time.
I then back that with another coat of clear, then onto my primary color of Corsa Gray (Tamiya Polycarb), to look like faded/old seafoam green.
If you want to go this route, you should prepaint anything that you don't want to have rust on it (ie: wood bed-liner). The next time, I will use much more nutmeg and create a more rusted body, but this was a trial.
I then picked up some crafting wood to build removable bed-rails, and a farm set to go along with some accessories that I already had.
I then cut the interior from my Bronco build to be more compatible with both bodies. I still need to paint the wood rails, but it's good for now.
All that is left for this truck is axle mounted lower shock mounts to create more stability. I can probably use the cheap Tamiya grasshopper mounts.
