hi guys, ive started to use an airbrush recently to weather my BR blue locos and stock. have any of you come across any useful vids online that could help me to get it right? there are plenty for OO gauge but im guessing air pressure/distance from model etc will be different.

cheers dean

You may find it useful to cut our card shapes to suit what you are weathering and practice on them.  This will get you used to distance, pressure used and good practice for your airbrush technique.
