You could use either this or the Candy Red to paint your Red Terror diesel. This colour is a weathered finish suitable for in service diesels...
Paint is at correct consistency for airbrushing. A 0.3mm needle at 15psi is a good point to start experimenting. Cleanup is with any generic lacquer thinner.
