I have aan Iwata HCS airbrush I want to do very thin lines. Do you have any recommended paint-thinner ratio for Gunze Sangyo paints??
Any hel will be greatly appreciated

Well, the bottom line is that you’ll just have to practice and see what works best for you. I use mostly enamels, and I’ve never used Gunze, but I like to mix my paints pretty thin. I shoot for about the consistancy of skim milk, maybe thinner if I’m trying for very tight detail. I can’t imagine that enamel thinning would be radically different than thinning Gunze or Taimya or just about anything else for that matter. Start with a mixture about the viscosity of whole milk, and spray for a bit, see how you like it. Then add small amounts of thinner and spray each mixture, eventually you’ll come up with something that will work for you. It won’t even take as long as it sounds, I promise. Good luck and happy experimenting.
Maddafinga basically covered it. I too have found that it seems better to err on the side of two much thinner than not enough. I would also emphasize the importance of doing test spray on scrap plastic prior to painting on your model. Sometimes you’ll have a paint mixture that looks perfect, but doesn’t spray well. At that point you need to adjust the mix ration until it sprays right, regardless of it seems in the color cup or mixing jar.
On my most recent project, a MK-I Spitfire, I thinned out some ModelMaster Duck Egg Blue for the underside. It was fairly thin out of the bottle, and I thought that I had seriously over-thinned it to the point where I added a bit more paint to it. So I was quite surprised to find that the thinned paint was barely passing though the airbrush and laying down kind of lumpy in a manner consistent with underthinned paint. I added a bit more thinner and tested, and had to repeat the process several times until I was spraying something that looked more like colored water than properly thinned enamel. In spite of the apparent over-thinning of the paint, it went on beautifully and covered well.
