Right on, Gryph...the few paint jobber shops here in my neck of the woods were nowhere near as helpful. I guess I didn't speak the language of paint and the help just wasn't going to manifest. If only. I guess I caved when "price for paint" dollar figures were thrown around and their lack of enthusiasm for a noob novice. Pushed the Easy Button and learned a lot about my first paint attempt...
Paint guys are always leery of a new customer coming in with a strange paint code for an old bike that they probably never heard of. That can lead to expensive, for them, jobs trying to mix a formula with nothing to tell them if they are getting it right. Unless you are repainting in a different color ALWAYS bring a part with you that they can visually match along with the color code on the bike just in case they have it in their data base. Even if it is in the data base, a part will help them determine if they need to correct to match any sun fading that may have happened in the past 30 years.
Also keep in mind that the code on the bike is the color scheme, and not the actual paint code. You need to look up the paint numbers on the internet to get the correct numbers for your color scheme.
If you are doing a repaint DON'T use a BMW bike color code. Look at the cars around you. When you see a color you like on a common late model car take a trip to the dealer and check the color code for it. I personally like Ford colors, and they are common enough that paint guys don't have a problem mixing them. I used two Ford colors when I did the faux SE paint job on Moby Brick Too.
The paint itself isn't that complicated. Acrylic enamel automotive paint is what I use. It's mixed 1:1 with medium reducer and applied with a cheap Badger airbrush. I like the airbrush because it is almost impossible to f*ck up the base coat with it, and I can clean it in about two minutes with an couple tablespoons of lacquer thinner and some paper towels. Another nice thing about the air brush is that it uses very little air and can run with a very inexpensive compressor. Harbor freight has small units that will work with the Badger for only $40 when it's on sale:

I like the rattle cans because they don't require adjustments like a gun to lay down a good coat of paint, just shake and spray. They also don't require any cleanup when I'm done. Another benefit is that I don't have to worry about them flashing in the gun if I can't do a follow up coat right away. This is the stuff I use:

It flashes for followup coats in 5 minutes, and can be handled in about an hour. It cures to a good finish that can be sanded and polished in about an hour, and gets really hard in a couple weeks. I try to paint in the fall so the paint has all winter to really cure before the bike goes on the road.
If you want a better than factory, show bike finish, apply 4 or more coats of clear, wet sanding any runs or orange peel with 800 or 1000 grit before the last coat. After the last coat wet sand with 2500 and buff out with 3M Perfect It EX machine compound:
