Making a cigarette boat.  The paint job is pretty cool I think.  Would love some thoughts on how to go about it;

hand paint it with gel/vodka?  Marble the fondant? Cover in turquoise and add super thin strips of violet and darker blue?

Thanks!

I will suggest airbrushing dark blue over turquoise and then add then brush thin stripes with vodka or lemon extract.  Please post your final pictures, would love to see how it turned out.

AI would definitly go with handpainting in gel and vodka. It's the only way in my opinion to get those lines right where you want them.
