Please, give it a try 
The only thing to do is not waiting too long to wipe the ink, the more you wait, the more dark and "drawn" looking you'll have on the mettalic surface.
I'm sorry to not have better picture to show you guys. It was done almost 5 years ago with a very nasty APN.
And take a look at my ISS Enterprise. The improvement is "visible" and it's the same technic only with finest "H" or "U" letters. But definitly quick and easy, since I did the two kits, each one, in 2 days.
The clear parts were not painted, the red, the blue and the green were done with simple markers you can find in every shop.
