Daler-Rowney flow enhancer.

I bought a bottle of this after  seeing a  recommendation  of it on a forum  I  looked on while looking for a colour I was needing.  I  am quite happy with  how this stuff works, really.  No brush  marks when driving the  hairy stick, tamiya acrylic paint goes on nice  by brush, which is a  nice  change, and it is good in airbrush use too, really  does do what it says on the bottle and has given me a bit more faith in the  hairy stick

Not thought of using flow-enhancer Chris. Could well be useful especially with Tamiya applied by brush.

I'll invest in some next time I'm near the art shop. Ta for the heads up

I was pleasantly surprised by the difference it makes  Chris, I think that  experimenting with the amount you  put in will help to get  the paint how you  want it.  I have put some  in some of my vallejo paints and lifecolour paints. The lifecolour stuff has taken a  back seat since I  started using  the Valle  I must  add.

Cheers mate. My go to paint for camo schemes is now the Hataka Blue Line, but I still like Tamiya for primary colours in particular. So I'll get some for that as Tamiya can start to dry out a tad quickly from my point of view.

Thanks for this tip - I'll see if it's available here and have a go.
I tend to steer clear of Tamiya for brushing, as I can't get the jolly stuff to play nicely, but this might be the answer for me.
