Tank and rear fender.
A little old is the paint of the concept because it is worn by the pan head of the beautiful eyes.
Flame only on the tank.
It was colored with a fine tarric and painted like unevenness.
Candy color paint like unevenness with airbrush using 2 colors.
As "a little old" so do not overdo it.
I tried expressing "a bit old" by hand-polished with a coarse compound.
