I'm sure you guys are all aware of the problem with brushing Tamiya acrylic paint and I was wondering if anyone has found a solution. I have tried using Tamiya Laquer and X20 to thin the paint but I still cannot get any kind of decent finish using a brush. There is a Tamiya thinner that includes a retarder but it seems to be very hard to find in the UK.

I have had no problems at all with airbrushing Tamiya but occasionally I need to involve a bit of brushwork and this usually means trying to mix up some Vallejo paint to match.
