The Tamiya paint numbering system seems to have its lineage from the old Pactra enamel paint line. The colors are very close to what Pactra had with some minor differences. Tamiya used to recommend Pactra paints before they introduced the Tamiya paints.
My technique for brush painting with Tamiya acrylic is to lay the paint on very wet with a broad paint brush. Then use the paint brush to spread the paint for coverage but once stop brushing once the parts are covered and just let the paint level out. The problem with the Tamiya paint is that when you start brushing over a section that is starting to dry then you start lifting it.
Personally I haven’t really had that many problems with the Tamiya paints and brushing them. I have to weather a little bit harder but never anything major as far as looking bad. But I haven’t had that much luck with the Spray paint. The problem I have with them is that they come out with to much of a shine. Makes your models look like they came straight off the factory showroom floor. But again weathering can normally take care of that. Now that I have been reading these post tho I think I may start using the model master paints. Maybe I wont have to weather as much.
Wait is there such a thing as to much weathering a tank?
