I don't feel Tamiya is coarse in anyway...but it is certainly watery in consistancy. The watery nature is what, in my view, make it a less than ideal choice for brushing, unless you have either: some fairly decent brush aptitude; or are very patient with multiple coats over several days in order to build up opacity. My suspicion is that Tamiya will make a better airbrush paint than brush fodder.

I have read very good comments about Gunze Sangyo, but my hobby shop didn't have any.

Now as for a can of worms...for my personal preference, you just can't beat acrylics over enamels. I base this solely on toxicity and no need for harsh thinners/cleaners. That's just my gig, though.
