That's been my understanding. The control is supposed to be outstanding and as you say, if it's just simply easier then why not. It's a little bit different spraying on hard plastic versus paper or another medium, but you just find the sweet spot and you're good to go.Most airbrushes can make very thin lines. Even with my 0.5 Eclipse I can do eye lashes on a A4 portrait. The Micron just does it so much easier.
Let me ask you Andre: I've seen a review comparing both brushes from a guy I trust implicitly spraying on plastic models and he sees no difference between the two, but if it were up to you, would you spend the extra $200 on the Micron or would you just get the Gunze?
