Let me know what you think of the comart. I've only used CI but bought a bottle of MFX and comart and am definitely thinking of switching to one of them. I get zero tip dry with MFX or comart but after 3 secs my needle is covered in paint when using CI.
Com art is my favorite paint. It does want a slightly porous surface (like I have problems on my resin kits with it), and it's really fragile, but it sprays like nothing else. I bought a color wheel set of Createx Illustration and I think I wasted my money.
Don't bin the Createx just yet, when I started I had 'issues' with it, I bought Etac EFX (same as MFX that's EFX branded /tweaked by Marissa) and my learning improved quickly, once I got comfortable with how paint should behave, what sort of consistency /psi I needed I slowly started using the createx again and go on with it a lot better. Now I comfortably use either.
