To get the right paint for your vehicle, you need to find the paint code for your car. It's usually located in a doorjamb, inside the trunk or some other hidden location. If you can't find your badge, check the owner's manual or call your dealer. At the auto parts store, match your paint code with the code in the paint-matching guide. It's a good idea to keep a small container of touch-up paint handy for minor nicks.
Some automakers even supply a container of paint in the glovebox with the purchase of a new car.
These containers often come with a brush attached to the lid. These colors match the original paint jobs, so there should be no worries about mismatching colors. Blisters you may encounter are evidence of underlying damage and must be removed. Bevel the edge of the paint around the spot to make the repair less obvious. Wash the area and rub it dry with a clean cloth.
