This is truly "old school" paint technology. Unlike standard metallics, which have the metalflake blended into the color, candy colors are achieved by applying several thin coats of transparent color over a metallic basecoat. At best, touch-ups are an iffy proposition...for a pro. Colorite sells the paints in rattlecans. IMHO, the cost & complexity of such a project strike me as far beyond your budget & expertise. If you're just after a nice-looking paint job, you'll be happier (and richer) using a standard non-candy color.
I'm not trying to p**s on your parade, by any means. You have a refreshingly "old-school" mindset when it comes to stretching your abilities on the bike projects you've outlined in this forum. Maybe a candy paint job would be a good learning experience for you. The last think I'd want to do is dampen your enthusiasm. Can't help but think that it's more likely to be a "trial by fire".
If you're bound & determined to work with candy colors, then the best suggestion I can make is starting out with a small test piece. If you're trying to touch-up chips, maybe try one or two in an inconspicuous location. Either way, if the results are a disaster, no harm/no foul.
