I used a red scotchbrite pad and sprayed 3 coats of satin lacquer on the interior pieces of my 47. Keeps my clothes and hands clean while driving it. As for the exterior, I'm with the other guys here, leave it be. I use Gibbs Brand penetrating oil once a year to preserve it. Spray it down and wait a week then give the truck a bath and off I go.
Another suggestion is to wax it with a good carnuba wax with the surface heated to around 100 degrees. It's supposed to melt the wax into the rust and offer a good layer of protection.
