Okay I see…
I kinda like the look with the painted silver/gun metal recessed lines (see biceps part 501st crl) …probably will go with gun metal color and weather with black enamel wash…
Shallow grooves are present in a pattern matching the photo.
The grooves may be a matte black, metallic black, matte silver, or gray.
If coloring is used, the shoulder bells, biceps, forearms, and thighs must match.
