Been a long time since I made progress on this but got my ammo modulation set through so time to get cracking.
First was a coat of Tamiya fine surface primer to all the photo etch and metal parts. Then a base coat of gunship grey to serve as the metal coat.
Next after it had cured a coat of hairspray ready for the 4bo base.
The mig set has four colours, dark base, base, light base and highlights.
Dark base:
Base:
Light base and highlights
After this I added some of the dark base as streaks and post shading.
Final result with chipping
That's all for now
