So I didn't quite know where to post this information, so I guess I'll post it here.
A friend of mine is a professional painter and I've been talking to him about painting my newly acquired 919 a pearl white and powder coat as much of the other metal a flat black. Anyways, he sent me an email describing a lot of things that you can consider when looking into paint. I thought it was very good information so I thought I would pass it on as I know a lot of people have considered custom paint jobs. ENJOY!
Before we get into the products I will be showing you, let me give you a rundown of what is available in the paint world as far as types of paints and paint systems.
First of all there are some terms I will be using, here are the defenitions.
: To maintain color after being exposed to light (sun) for a period of time. The more light fast the product the longer it will resist fading.
Single Stage Paint System
: A paint that has a base and a hardner usually will not need to be clear coated, but will not be as protected.
Dual stage paint system
: A system in which a base coat color is sprayed no hardener added then clear coat is added for protection.
Durability & Longevity
: The ability of paint to last in its surroundings mainly road debris (rocks, sand, rain, salt) etc.
: How shiny the paint will be for example flat or glossy, there is no standard in the coatings industry so for all intensive purposes you will want a gloss or a super gloss for a nice shiny finish. When they talk about flat paint like hot rod flat it is usually a satin finish. Mostly the simplest measurement of sheen goes like this (measured in percent of refractured light back compared to the the angle that it enters)
Flat 0-9 percent refractory
Matte 10-25 percent refractory
Satins 26-40 percent refractory
Semi gloss 41-69 percent refractory
Gloss 70-89 percent refractory
Super gloss 90 percent refractory and above
Most automotive paints fit into the super gloss category but are usually only called gloss
: Oil based paints used mainly in industrial not used in automotive rustoleum is an alkyd.
: Old school, not very durable, not very light-fast, super gloss show room finish.
: Used as a single stage system always uses a acrylic paint and an oil derived isocyanate hardener, not often clear coated because of compatibility semi durable not very light fast come in a variety of gloss levels
Urethane single stage
: Used as a single stage system uses polyester or certain acrylic paint and high purified de-isocyanate hardener, not often clear coated but usually compatible more durable than acrylic enamel semi light fast come in a variety of gloss levels.
Urethane base coat
: Used in dual stage system and is not an effective coating unless clear coated is an air converted product unlike single stage urethane which are chemically transformed. Gloss level is usually lower than gloss so that it can be clear coated easier.
: There are many types of clear coat ranging from acrylic enamel to Urethane (hardened) different formulas affect the quality and durability polyurethane is commonly used in automotive but it is urethane paint. Clear coats have different additives. Clear coats are basically the same as the paints in which category they belong only without any of the color pigment.
: Usually a urethane base coat without pigment used so that you can spray over graphics so that you can tape over. Must be clear-coated.
: High concentration of pigment in a urethane paint give deep color and allow light to pass through because they are transparent.
: Affect the overall effect of the paint metallics, pearls and chamellions usually coated silica in different shapes sizes and the coating on top of the silica crystals affects the effect of the paint because of how it interacts with light. There are thousands of different types of additives and the cost and complexity to make the crystals affects the price. There are other types of additives like thermo-chromatic and phosphorescent to name a few.
Here are some links to some paint.
This first one is a full kit of acrylic urethane paint and clear one gallon of each and all the reducers and hardeners with it. I figure you will need a quart and a half of each so this is more paint than you need but the prices might be close compared to local paint stores if parts are already a light color like white or light gray then you may only need one quart kit of color. Add more clear for more protection at least 2 quarts. This is the cheapest for what you get anywhere.

The next set of paints are from tcpglobal.com. The platinum white pearl base coast will need clear coat also.
The next set of paints are additives so you can make your own mixtures of paints, they can be added to any paint or clear coat. These products allow you to buy a regular color of paint or plain clear and you can add these products to make your own custom paint. It can be a less expensive way to make pearlescent or flaked paints:

So here are a few options that may give you some ideas. Paint seems very simple but there is alot to consider.
