Repairing a car after a collision is only half the job. To get an
automobile back to its original condition, fenders, door panels, and other
repaired parts must be painted to match the rest of the car. This is
tougher than it sounds because matching new paint to old paint requires
patience and skill.
Paint for cars doesn't just come in a can that matches the original car
color. Most paints are made up of several different pigments (colors) that
have to be mixed together to get the right color. Every car has a color
formula. With the help of a computer that calculates the exact amount of
each pigment needed, the technician can match colors exactly.
As an auto body repairer, you need to understand the process of measuring
car paint, even though a computer performs the calculations. The following
chart shows the mix of pigments needed for six ounces of Viper Silver
Metallic paint to match two car doors. A computer provided the paint
formula and the exact amounts of pigment that are needed for the paint
mixture. The paint code, the color, and the number of grams needed of each
pigment are given.
Black paint mixtures for cars are measured in grams, even though the paint
container may be identified in fluid ounces, pints, or quarts. Grams
measure weight and fluid ounces measure volume. A container that holds six
fluid ounces can weigh different amounts. Six ounces doesn't sound like
much paint, does it? Surprisingly, it doesn't take much paint for two car
How much of each pigment is needed for four ounces of Viper Silver Metallic
paint? To calculate the grams of each pigment in 4 ounces, these are the
things you need to know.
