Thanks guys for all your kind comments.
Ian, I paint all my rigging lines after they have been fitted but care has to be taken not to get paint onto other painted surfaces. The Mr Metal Color paints are lacquer based so are very thin, if you are not careful when painting your rigging lines the paint can easily "flick" off and land on places where you don't want it to go. To avoid this i cut paper to fit under the lines, the paper is cut as wide as possible to cover as much of the model area as possible, moving the paper as you run the brush along the line also helps to reduce the risk of paint getting onto the model.
Work on the engine has come to a stand still at the moment, I am STILL waiting on a delivery from RB Motion of some more small brass nuts, hopefully they will arrive tomorrow.
