First off beautiful bike. I have a David Kirk built Fishlips bike that also painted GIOS Blue with the red primer.
While looking for touch up paint I found many references to Sinful Colors Endless Blue fingernail polish being a perfect match. That was the case on my bike. Just sharing the info since there's so many paint comments above.
This shot from before I touched it up shows the blue color and the red primer under it. Supposedly this was painted at Dave Kindig's shop in SLC but they didn't respond to my query.
