Printing my own..... new territory

Hello!

There are companies on the net that do decal printing, ant they usually do nice silver and gold. Here's a pic of a truck cab that has decals I designed and later they were custom-printed for me by the German company Decalprint:

Good luck with your builds and have a nice day

Another possibility would be to paint the gold. Then print, on clear decal film, the red logos and two colors of the belt line and place the decals over or adjacent to the paint 

Gold is pretty hard, but you can approximate it.  Find a good color photo that has some nice gold areas, import it into your graphics program, and grab the color of the nicest gold area in the picture.  You should probably do some test printings on regular paper to do fine tuning on color.
