Update
I was going to do some step by step-
but I’m not that talented and frankly it’s far too boring
I primed with some acrylic Grey, mid toned with flat black and went over the high points with Light Gull Grey
Touched up sparingly with some silver & Gold paint pen and used a Really cheap shaped brush to accent with insignia yellow hazard lines
Nothing fancy- honestly total cost was about $3.00
Grey Paint $ .99
Rose Art assorted brushes $1.99
The remainder was trash bits
