Once all of the panel line wash has been applied and allowed to dry completely (24 hours), it's time to start airbrush work on the body. Using the same Railmatch frame dirt as before, but mixing it with a little Railmatch weathered black, a very light misting is applied to the whole locomotive. Side, ends, top and underparts. This is deliberately not perfectly even, more being applied in some places than in others, because I don't want the end result to look as if it has had a perfectly even coat of paint airbrushed onto it.
You can see by looking at the roof in particular, that this process has added a dusty texture to the paintwork. Care has to be taken not to overdo this in 4mm work and below, but from 7mm upwards it becomes more necessary.
There will be a break in this blog for a week or so, while I spend a week at Missenden Abbey Railway Modellers' Summer Retreat and get on with some . . . . er . . . . . . weathering.
