the paint im using is watered down railmatch acrylic, Frame dirt and sleeper grime with a little brake dust on the bogies.
one thing i will say is the colour differences in the sleeper grime and frame dirt is minimal to say the least!
i stripped all the paint off for a second attempt, the underframe im happy with the roof im happy with (just need some black for exhaust stains) but the body is naff!
i still cant get the paint to blend in without the difinative line. it looks too thick and splodged even though its watered down layers!
ive been looking at pictures of a dirty 47 trying to recreate its thousands of miles work, not just slapping paint over which it looks like!!
so night 3 im back to this
just gotta finish removing the dodgy paint on the yellow front panel!
Geoff, i did try waiting until the paint was almost dry then trying to fade out with water as per your method but once the acrylic was almost dry and i added water it pulled great chunks of paint off, hence i tryed watered down layers.
any more ideas that might help? (apart from an airbrush !)
