Yep, I do just that. Currently using a cheap 'brush from which the Iwata design team based their products, mine having been around for at least 50 years.
Get in close, and relatively low pressure (around 12 to 15 psi), and fine lines are no problem. In fact, when doing a soft-edged demarcation, the line is so fine, I have to use a spaced mask to get the 'feathering' effect.
Wider bands realistically fall into the area of around 1/2 to 1 inch, although up to around 2 inches can be achieved, in a thin coat, if used as described by Steve, with the larger nozzle and needle supplied with the 'brush.
There's absolutely nothing wrong with buying an expensive 'brush such as the Iawata range, but as I've mentioned a number of times, this type of 'brush was originally intended for hard, daily use in the graphics industry, and for modelling use, it's really rather 'overkill', a little like taking the rubbish to the tip in a Rolls Royce, where a Ford van would do the job equally as well.
I had considered investing in a more expensive 'brush, but couldn't see the point, for something used a dozen, maybe a couple of dozen times a year, when I could obtain a 'brush which would work equally as well, for a couple of years at least, and costs around a tenth of the more expensive products.
Certainly worth considering if on a budget.
