Thanks for the update Steve. I did not realize they closed the other topic.
I checked mine yesterday and discovered that the side frames are screwed onto the trucks. I removed them and sprayed with Rustoleum Matte. The pilot is also attached with screws but you would have to drop the truck to access them so I wrapped the engine and hit the pilot.
I'll post more pix later. The frames are sprayed but not the pilot for comparison.
