@yiha
i try to help u answer ur question.(hopefully i'm not wrong)

1. OOB=Out of box
(simple painting, lining)(which no included mod)
2/3.Tamiya paint mostly is enamel or acyclic(water base)
for enamel can be thin with tamiya thinner. and acyclic is water(as i know tamiya thinner also can)
4. depend, some people just "agak agak" some said thinner:color/1:2( i'm the one agak agak / need someone more pro to answer ur question)

if u wan to use water base acyclic. as i know need to apply alot layer due to the color is very light. need to apply alot layer.

as for yiha..
u r asking thinning paint for brushpainting or airbrushing?
for airbrushing is usually thinner:paint 65-50%:34-50%
u need to adjust urself as diff ppl tend to have diff preference..

Is this any good?
