Totally agree with your tips except that undercoat colour depends on what colour you intend to have on topIf it's a light colour, white all the way - else - black if you want black on top - black also if you're going to paint silver on top (matte)
Mr_K : Admirable effortAs blackie mentioned - there are bits where the red is showing through - bits where it's the joints - if there's paint rub - the only way around is to sand the joints so that it's thinner BEFORE the paint so that by the time the paint is on, it's around the same 'thickness' as pre-paint. With regular areas, just make sure you coat him with a uniform coat of paint, and yes - more layers if required. You may want to dilute your paint for a smoother finish. Jin Saotome's tutorials helped me get started about a year ago, so I recommend that! (jinsaotomesdangeroustoys.com)
