This 1/100 Master Grade Aile Strike RM Custom is a project by Renz Funtanar.
Here are the steps he did and he even shared the paints and weathering kit he used.
For the inner frame I used Vallejo Premium Gunmetal and for the shading i only used Tamiya Weathering Master Type F (oil stain effect).
This is how I made this build:1st – Removing Nub Marks
2nd – Panel Lining (using Tamiya Panel Line Accent and Copic Marker 0.05)
3rd -Applying Decals (Per Piece ex: part A-1)
4th – Shading (Per Piece, using Tamiya Weathering Master Type D oil stain effect)
5th – Flat Clear Coating (Per Piece)
I know its a lot of process and it might even test your patience but its all worth it when you fully accomplished it!
