Types of paint:
 * The newest auto paint technology has brought us non-toxic water-based paints. These paints are the most versatile of all, able to be applied to metal, primer, or to an existing paint job. Water-based auto paint is especially popular for use in adding graphics to a vehicle or motorcycle, but can also be used to paint the entire vehicle.
 * Like enamels, urethanes can be used alone or in multi-stage paint systems that utilize a final protective clearcoat.
 * Urethane paints are newer than enamels, are more expensive and more trouble, but they lay down easily like lacquer while having the toughness of enamels. This auto paint requires three products: the color, a reducer to thin the color to the right viscosity for the spray gun, and a catalyst used to accelerate drying time.
 * Lacquer-based auto paint was popular between the mid 1920s and 1960s, and is still available today, though it has become illegal in certain areas. Lacquer paint is cheap and goes on easy for the inexperienced painter, plus it provides a nice high gloss. However, it also chips easily being a relatively “soft” paint, and it doesn’t stand up well to UV and chemicals, making it a short-lived paint job. Lacquer auto paint is available in aerosol spray cans and for use with spray guns, but is not generally recommended.
 * Enamel paints dry to a hard shell making them tougher than lacquer paints. Professional shops bake on enamel paint in heated bays or "ovens," but enamels are also available in aerosol cans and for use with spray guns. Enamels, while tougher than lacquer, do not lay down as easily as lacquer paint, making them trickier for the Do-It-Yourselfer (DIYer) to apply.
 * Clear coat paint, or a clear coat finish as it is commonly referred to, is actually just paint that does not contain any pigment or color. In most cases, clear coat paints use specialized chemicals that allow easy adherence to flexible components such as plastic bumpers. These types of paints usually also include UV inhibitors that help to prevent ultraviolet sun rays produced by the sun from fading the color of your vehicle. Many times, these types of paints are made from you urethane or polyurethane which also helps to give the vehicle a`` high-gloss or shine.

How car paint bonds to different surfaces:
 * Fiberglass: Use polymers (plastic based paints)
 * There are two types.
 * 1) Uses exposer to air
 * 2) Uses a catalyst, heat and air
 * These paint types are basically plastics in a volatile liquid. They adhere well to epoxy resin, vinylester resin, and polyester resin as long as those resins are dry to the touch.

 * "Stone chips detract from the appearance of your car but also can provide toeholds for rust to begin."
 * Why you can't use house paint on cars
 * People generally want their cars to shine. House paint doesn't. Most house paint is latex which doesn't stick to metal real well.
 * My dad also said that some paint is water based so it wouldn't last very long.
 * How it stays adherent.NEW METHOD: []
 * The "binder" or resin is what makes the paint stick. It imparts adhesion, binds the pigments together, and strongly influences such properties as gloss potential, exterior durability, flexibility, and toughness. Binders include synthetic or natural resins such as acrylics, polyurethanes, polyesters, melamine resins, epoxy, or oils.

 * It's not the paint that rusts, it's the metal under it- when the metal is exposed to water or is unprotected from an under coat.
 * powder coating vs. traditional methods
