In a few recent builds – including the KV-2 (which is currently on hold) – I have noticed that the paint finish in certain sections was a bit rougher and grittier than I would have liked. Reading around, it seems that I need to thin the paint more (even though I had been using Tamiya’s recommended paint to thinner ratio) and try to spray in more, thinner coats (1:1 paint to thinner). This is all good advice and my tests with Tamiya paint seems to bear this out.
However, I also wanted to try a different paint range and for this build selected the Mig AMMO paints.
Primer: Wanting to move away from using spray cans as much as possible, I decanted Tamiya “Fine Surface Primer” (light grey) from the can into a glass bottle, according to this guide. I reckon about an hour is good enough for degassing of the liquid, after which I sprayed it on with airbrush. This time I did thin it down with lacquer thinner (two parts primer to one part thinner). I think for my next model I may well just spray the neat liquid.
Base coat: AMMO “Russian Green Base” (A.MIG-932) was sprayed straight from the bottle in multiple (at least five) thin coats, leaving 24 hours drying time between each coat. I must say that so far it has produced a nice, clean finish. I think for this build I will not be adding any highlight coats on exposed features (basically I don’t want to push my luck!) but rather rely on subsequent weathering to break up the uniformity.
The varnish layers are still to come and entail further testing.
