Tamiya xf-62 olive drab

Add a little bit of Tamiya retarder and Tamiya acrylics will be great for hand-brushing.

All you have to do is just keep it "wet". Dip your brush in water every 5 minutes, dab it off on a paper towel and it will be fine. Alternately, just mix it every 5 minutes or so and the thinner medium is redistributed and it brushes fine,

I'll give it a go tonight, thanx doog

Once an area of previously applied paint starts to dry (you can tell by the sheen on it), don't attempt to paint over it otherwise you'll pull it up in big ugly lumps. Only paint to the most recent wet edge.

If the coat is uneven, don't be tempted to paint over it. Allow it to cure overnight before applying the next coat.

Good question I even add some Windex Original formula in a plastic Pallet and test it on a Sprue for coverage 

I use Tamiya's proprietary acrylic thinner, when I apply Tamiya acrylics by hand.  They're meant to be airbrushed, so they're meant to be thinned for use.

I can't speak to using a retarder, since I don't use one.  I find it sufficient to dip my brush in the thinner, and then into the paint, and apply it.  Or, I'll put a couple of drops of the thinner in a well on my ceramic palette, load up the brush with paint from the jar, then use that to get the paint into the thinner and make a little batch of thinned paint.  I can apply Tamiya paints in coats as thin as if I had airbrushed them.

Thank you, I will try that tonight.

Tamiya retarder - will try that ASAP!
