Only tangentially DIY, but are any of the beginner kits rated? You know the airbrush ,compressor, cleaning tools all in one kit.
Not requiring one of the whoop-e-do brushes at £100s so was thinking more of the £40 region then if I catch the spraying bug can get one of the better (and Dearer) brushes.
Range of uses :- Some modeling, some (very small) touch up work and some RC stuff (mainly Lexan car bodies ).
