My powder job is the orange bike on my profile pic. I think it's fantastic. I can spray paint, I've done a couple of cars in my time but I don't kid myself that my skills can match the powder in the pic. Apart from anything else you'd need 150 coats, it's a very thick, durable film. Price up a litre of primer, a litre of top paint and thinners, rubbing down gear, you'll get a shock compared to powdering. Don't even think about aerosols, you'll be into £40 before you blink and it will still look rubbish.
If you have spray gear and you want a cheap job, mix household white gloss with househul red gloss to the right colour, thin it heavily with white spirit and spray it hot (need a portable electrical ring), it goes on like cream and covers a multitude of sins. It also dries slightly soft so it's more stone chip resistant, and it has a high solid level so it's robust. I used to know a couple of blokes who did cheap resprays like this - any colour you like provided it's white - and they did OK. This was back in the days when used cars were still worth a little bit of money and a cheap respray was worth contemplating.
