Build Log: KV-1 painting After priming, I have airbrushed everything with Vallejo Air paints, mixing colors to create slight modulation. I sprayed the model with the AK Worn Effects fluid (similar to hairspray). Then I masked off the camo sections with blue poster putty. I sprayed the model with Polly Scale IJA Grey.The putty peals off easily. Any extra residue can be pulled up by placing more putty on top and lifting off again.I applied water all over the model and waited a minute or two. Then I used a hard brush to begin chipping the paint.I added deep chips (dark rusted metal) via a paint brush and Vallejo German Black Brown color.Used AK DAK wash as a filter.Added dust and rust streaks via AK effects.
