Notable products used:
The recommended Tamiya paints were airbrushed using a Badger 155 Anthem.
Micro-sol for the decals
Mig Productions Chipping Effects
Mig Productions pigments
AK Interactive OIF brown wash
AK Interactive Engine and Metal Weathering Set
Several of the steps used I had never tried before and were over-/clumsily done, specifically the chipping and spraying the mud along the bottom.
The sprayed mud came out a different colour to that on the tracks, due to colour change when the pigment dried.
I had no oil paints to filter with so used the OIF as both a pin wash and a filter. I think that worked well, although I have bought oil paints for next time.
Overall I'm really happy with the outcome.
Photos: These were taken with too narrow a focus; I'll improve that and the background next time.
