Updated April 17, 2017

One important step in the lengthy process it takes to successfully paint a car is mixing the base coat of car paint. Mix the base coat wrong and you will end up with a flaking, peeling paint job in a very short time. Mix it correctly and your paint job can last years. Learn the correct way of how to mix base coat car paint and add a quality paint job to your car.

Place the clean measuring cups on a flat surface. Pour the desired amount of base coat car paint into one of the cups.

Pour the reducer into the other clean measuring cup, measuring to make sure the reducer amount is one-quarter of the amount of base coat car paint. Most base coat car paints are mixed at a ratio of four parts paint and one part reducer.

Mix the paint with the reducer and stir very well with the stir stick. Pour the mixture into the can of the paint gun.

Tip

Read the directions on the label of the base coat car paint to make sure it doesn't require a special mixture ratio.
