10. draw the light grey detail with white pencil on back panels, liquid mask
11. masking tape the whole helmet except back panels

13. outline silver damage on back panels with sharp pencil
14. liquid mask silver damage on back panels
15. spray grey no.79
tip: if the silver is not surrounded by grey, leave the liquid mask on! The grey damage within the silver on the R/H panel will be added as an individual layer later.
I think its a combination of the way the liquid mask adheres to the metallic silver, almost with a fine ragged edge and the thickness of the next coat, that and keeping the detail as small as possible and even omitting parts that are too fine; these areas can be scratched in later. I left the grey layer 12 hours before the mask came off, this also played a part...
