Vine’s book is certainly an interesting and worthwhile read. His results are near perfection but some may be rather daunted by his no-compromise approach.
I could never see myself achieving good results with a brush, except on quite small components and maybe spoked wheels. For platework etc. I have a cheap Badger airbrush (~£20,) which gives quite acceptable results by my standards. I’ve used Precision Paints and Humbrol gloss enamal, although this latter seems less widely stocked these days.
Rattle cans can give reasonable results with practice.
A good-sized workspace and a decent airbrush compressor are nice things to have.
