Plastic Car Paint Techniques for a Professional Coat

January 27, 2012

Plastic car paint is used for all of the interior parts of your car that may fade or dull over time. There are exterior plastic surfaces as well that may be able to undergo the same painting techniques. If you are in need of a fresh look for your car, consider some of tips listed below to get a professional look. With the right materials, equipment, car paint preparation and patience you'll be able to get those plastic parts on your car looking brand new again. 

Buy the Right Paint and Materials

You will need to go to an auto shop where they will have a variety of different colored enamel paints that will work well on plastic. Get the color you want, a paint solvent, primer, towels, plastic paint car cover, paint gun, 400 grit sandpaper, paint thinner, goggles, respirator, clear coat paint, car paint masking tape and a hat or shower cap. 

Prepare the Car for Painting

Put your car in the garage out of the elements, but make sure you have some ventilation for yourself when you start doing the work on your car. Clean the plastic that is going to be painted and dry it well. After you have done this, you are going to want to sand it with the sandpaper. Make sure this is done in a circular motion. Wipe off the plastic you are working on with a towel. The sanding will prepare the plastic to soak in the paint.  

Take the plastic car cover and put over the area where the plastic piece or panel is and then cut out where the plastic is making sure it is a little bit bigger than the plastic piece. Make sure to take car paint masking tape and attach the cover around the area that is going to be painted.  

Prime the Plastic

Take the spray gun and make sure that the psi is only 15 to 20. Read the primer paint and see just how much paint thinner you will need to add to the primer, to put into the spray gun and have it come out the right consistency. Put the primer mixture into the gun and begin spraying the plastic with a side-to-side motion. Do this until all of it is covered with primer. Wait 15 minutes before you put on another coat of primer. Continue until you feel there is enough primer on the plastic. 

Paint the Plastic

Clean out the spray gun extremely well with paint thinner and then do the same thing you did with the paint as you did with the primer. Once the paint is mixed, pour it into the gun and paint over the primer in the exact same way you sprayed the primer on. When finished, you need to check the gun and make sure it only filled ¼ of the way with paint and thinner. Fill the rest of the gun with blending solvent, and then spray a coat of that onto the plastic. Wait 15 minutes and do one more coat. 

Put on a Clear Coat

Clean the gun out with paint thinner and follow the directions on how to mix the clear coat paint so it can be put into the spray gun. Once you have done that, spray three coats of this onto the plastic. Wait at least 15 minutes between coats. Let the plastic piece dry at least for a couple of hours before you take off the plastic paint cover you had protecting the car.
