I had this idea, i am pretty sure this is how it works.
Dark brown underneath, let it dry and then do a light brown and go over that with a brush or something like that. Is that how it works? This is with something like a sprocket. I kinda wanted to give it a shot bc i think it'd look good on my bike.
Has anyone done this? If so, let me know how you did it.
It would work to an extent and I have seen a "woodgrain" frame from a shop look like it was done in that method and it didn't look bad. Personally id do the lighter brown on the sprocket and then put the darker brown on the brush and brush it on.
Most "woodgrain" parts are hydrodipped though.

Airbrushing is the only way, unless you get a frame hydrodipped.
