Hi Frank,
I guess, it is difficult to get it in EU.
As alternate solution you can try a finish, as i did:
I have sprayed Molotow Burner Chrome (really cheap) acryl, the imitation of the rivets was done by using a 0.8mm kanule.
The polished section -needle end was cut by a microgrinder+diamond rotary cutter.
The resulting sharp edged micro tube is perfekt to stamp rivets into the chrome surface, the plate imitation is done by a cutter blade.
Set it on desired spot unter slight pressure and turn it, holding under tension, 2 times around. The outer edge cuts a 0,8mm circular pattern .
This does not work as perfect as using flite metal, but this Molotow grafitti colour has a very fine milled metal pigment, very near to alloy.
After processing as described you may cover it by clear acryl coating (spray), or weather it with grime out of a diesel exhaust using a soft small brush.
It´s a matter of few EUR, first you may test it at uncritical surfaces. You will be amized about the result, even it´s not perfect!
Good luck!
