Thanks all!

@ SPang: N yes, E unfortunately not.

@ Jim: I first thought, the frame was done as a raised panel line. That would be easy to remove. Of course it was not, but finely engraved.

So i took a half round scalpell balde and scratched carefully along the frame till it was gone. After that i used MasterCasterīs Sanding Sticks to polish it again. Then i took a polish fluid (for cell phone [or Handy, like we say here] displays from the electronic market) and polished it a bit more by using a cotton stick. The secret was, to polish the complete left and right window, as the part already was diped into FUTUTRE, that means it becomes milky first when polishing. The last step was to dip it into FUTUTRE again. Et voila, there it is

It took me over an houre though.
Not only the windscreen is looking Trumpeter like, all the rivets too, arenīt they? But i like it.
@ Piet: Yes mate, lots of carefully drybrushing. As soon as it is sealed in FUTUTRE iīll do a black wash to the dials. Perhaps some more black drybrushing, to darken the panel agian. It became a little to white during drybrushing the dials.
Cheers mates,
