you can get the paint from halfrauds but i'd recommend a local paint/motor factors.
whereabouts are you from mate?
i know what you mean mate!
shame you're on the other side of the country, could have helped you out with some paint.
as i said, try a local motor factors for the paint will probably be cheaper than halfrauds.
am guessing your car is 040 super white?
i got some 040 super white from a local motor factors. is a good match and was about £5-£7 ish.
i got it as a spray paint. spray the larger areas and just spray a bit into the cap and then use a sharpened matchstick to touch in the smaller chips
