First thank you for explaining all that, it's a lot to take in.

Today I purchased some vellejo paint and vellejo Airbrush Thinner the kind that comes in that little dropper bottle, they had another type called thinner medium that was this cloudy milkly looking stuff but I figured the airbrush stuff was what I needed..

I'm not sure if my ratios are the issue or if it's something else but for every one drop of paint I added two drops of thinner and mixed it in my airbrush paint chamber like I do with Tamiya paint (this could be the issue prehapes it doesn't work that well for vellejo), I know vellejo makes two type of this paint one that pre thinned for airbrushing and another that's not and would need to be thinned, the type I got was the non thinned stuff.

When I tried to airbrush it was a night mare, it would sputter, splatter, clogg, then come out supper liquidy, then barely come out at all, or any variation of the above.. it was like I said a night mare. Its made double the work as I'll have to go over the model and sand it and clean it up and spray a nice clean fresh coat.

I thought it was my airbrush so I switched from my higher end Iwata to a lower end no name brush that I use for primers and less intricate work but I ran into the same problems.. what shoulda took roughly 10 mins took nearly 45. And most of that time trouble shooting the spray of my airbrush.

Vellejo products are new to me, so maybe it's a learning curve but before I spray them again I have to sort this head ache out
