I have two mid-1980s cars that are in very, very nice condition. Both have metallic paint- one is 100% as-delivered and the other has had maybe 10% of it repainted as required (rust, etc.) so far but is now in the shop for more. Here's my $0.02 on your situation:
If I were you I'd be *very* hesitant to do any significant paintwork on your car. The more original the better, even if that originality is at the expense of "perfection". Unmolested, original cars are the best, better than 100% restorations in many ways (all it takes for the latter is a lot of money, but something's only original once).
If any of the problems are related to rust or other corrosion, then yeah, I'd get those areas fixed and the repairs blended in *by somebody who knows how to do that*. But no way would I repaint the whole side of the car unless it was absolutely unavoidable.
I waited a long, long time (over a decade) to find the right guy to do the necessary paintwork on my '85 Jag (Rhodium Metallic single-stage lacquer, a very unusual paint that caused lots of headaches for Jaguar). He's only repainting what absolutely *has* to be painted. It's a lot of small areas, but he understands the originality thing and agrees that this is the way to do it.
I've had countless metallic cars spotted in over the years. It almost always comes down to the painter and the paint...get both right and you'll never see it. But it can be hard to match old paint and there aren't *that* many good painters out there. But again, it absolutely *can* be done. We don't know how well the Jag's repairs are gonna match, but we're doing everything possible and hoping for the best.
Oh, and I'm not worrying about the chips on my cars (got two on the hood of the Jag from August of '86, I remember the exact moment they happened). As a museum curator said in an old magazine article- "real cars have paint chips", and he was talking about some *very* valuable cars. If a chip is rusting, get the rust stopped. If a chip really bugs you, try touching it up, but IMO a badly done chip repair looks worse than just the chip itself.
