The amount of coats depends on the paints you use and the colour of the plastic. For example, white paint will only need about 2 coats on white plastic but if it were to be painted on blue it may need 3 to stop the blue coming through the white. As a rule of thumb keep applying thin coats until you’ve got a solid colour.

I like to paint pieces either individually off the runner or to put them together and paint any small sections that are all one colour. I’m not sure how easy the latter method would be on the Hi-Nu Ver.Ka as it doesn’t have individual sections like a HG.

I always spray the parts individually, when spraying on the runners, you’ll be left with gate marks, these can be touched up by using a brush, but will never the less leave indications on where the part was on the runner. Or you have to be willing to sand those area’s down, taking a lot of time, and if not careful sanding of paint on certain parts.

As for the colors, a metallic paint is in my opinion always better for a giant robot, but that is a matter of taste. And the MG Hi-Nu Ver.Ka. has no blue on it, it is all purple, but most camera’s can’t pick up the blue. I’m building one myself and have some pictures posted in the What Are You Building section on this site. There you can see how the purple turns out when mixing the colors using the manual and the Mr.Hobby color range.
And as for how many coats, @Nick tells it like it is
