Well, I just recently do shading for all my kits, this Liger Zero is just an example. My friends asked me for the tutorial so I try to write here. Hope this helps.
For this tutorial, I use Wing ver.Ka shield.
And use these three bottles of paint.
First step, use Mr.Surfacer to do the thin layer of priming, then use the dark grey to use at the sides of the parts.
Then, just use the white paint to spray them to diminish the gray area, you will see how the paints will collide each other and having a nice shade of colors.
Another example for shade, first step I use primer, then give the sides midnight blue.
Then, I use Gaia Cobalt Blue to finish the piece.
So, that’s folk for today
