I've currently been seduced away from Sopwiths and Fokkers by the lure of modelling old Bugattis, Mercs and Delahayes and I have come across this wonder product.
Comes in pump action marker pen format with 1mm, 2mm or 4mm nib. Gorgeous real shiny chrome layer deposited on any surface.
Obviously invaluable for my 1/24 autos, but probably lots of places on an aeroplane where a touch of real chrome would be appropriate.
If you haven't seen it before, give it a look if your'e interested.
I'll attach link here. (Sorry about the sound content - you might want to turn it off!)
