Yesterday I noticed that I used the wrong paint for the darker color🙁 used HU126, should be used HU125🙁 But not all is lost: I airbrushed carefuly a very very thin coat of the darker color and now I'm satisfied.
Anti skid areas made of painted decal. Extra thick coat of dark grey paint. 5 minutes after airbrushing press 1800 micro mesh for producing of rough surface.
