How to Apply Metallic Paint to a Car Door

Metallic paint can be applied on your vehicle whenever its finish becomes dull. Car doors may need to be repainted more often, as they are more prone to deterioration. You can use either spay paint or specific types of paintbrushes to restore your vehicle, instead of taking it to a machine shop. Here are some easy steps to help you obtain optimal results.

What You Need:

  • Car detergent
  • Brush
  • Degreaser
  • Sander or sandpaper
  • Auto body putty and putty knife
  • Tape
  • Primer
  • Metallic paint
  • Paintbrush
  • Painting clear coat
  • Safety gloves, goggles and mask

Step 1 -- Clean the Car Door

The car door needs to be clean prior to painting, or the paint may not adhere properly to the surface. Remove dust and debris with a brush. Prepare a diluted solution with car detergent and apply it on the door to be painted. Rinse with several buckets of water. You may also use a degreaser, which will eliminate debris that is more difficult to get rid of with regular detergent.

Step 2 – Sand  the Surface

You will need a sander or fine grit sandpaper to make the car door surface smooth and remove any bumpy residue, rust or paint bubbles.

Step 3 – Fill Holes

Use auto body putty to even the surface of any holes in the car door. The putty will need a few hours to dry, so follow the instructions on the product and continue when the car door is completely dry. You may need to sand the surface again to make it smoother.

Step 4 – Apply Tape

Isolate the areas that require painting with masking tape. Make sure to cover the car door windows, the handles, and the trim to ensure that these will not be damaged by the paint.

Step 5 – Apply the Primer

You can opt for a spay primer. The primer should be applied on the surfaces that require painting. Wear gloves, mask and protective goggles to prevent inhaling any toxic materials and to avoid any skin allergic reactions that may occur after direct contact with the primer or paint.

Allow the primer to dry. The primer will make the surface more adhesive and ensure that the paint is more resistant.

Step 6 – Apply the Paint

Spray the metallic paint on the car door. Apply generously and evenly, making sure to cover all of the surface of the door that requires painting. Avoid the areas covered by masking tape. Allow the paint to dry. This may take 15 minutes or more, depending on the type of paint you use. If you choose to use liquid paint and a paintbrush, apply the paint with even brush strokes.

Step 7 – Apply the Second Coat

After the first coat of paint is dry apply a second coat. Allow up to 2 hours for the paint to dry. You can apply a clear coat as well, which will protect the paint. Allow the clear coat to dry and then remove the masking tape.
