Select a leather restoration kit. Find these online or inquire at your local auto retail store. Make sure your kit has all of these products and the color you need. The kits should come with multiple color selections, leather prep, finishing sprays, a spray unit, gloves, a palette knife and sponge applicators.
Protect your work area. Use a small tarp to cover other areas of your car from being exposed to chemicals. Another option is to remove the seats. Refer to your owner's manual or consult an auto detailing shop about how to remove the seats.
Prep your seats. Using the sponge, apply prep solution onto the leather and rub in with an abrasive pad. This process will remove the manufacturer's finish. Continue this process until you start to see the color lifting from the leather exposing the lighter color underneath.
Apply the filler. Using a palette knife, wipe a thin layer of filler into the cracks. Allow the filler to dry for about three to four minutes.
Apply the first layer of color. Using a small amount, take a clean sponge and work the color into the cracked areas. Use this step to focus on blending the cracks.
Apply a second layer of color. Use the same sponge to apply color to the entire seat. Use smooth, even strokes. Applying the color too thick will cause bubbles and runs. If you notice this, take a cloth and immediately smooth the surface. Allow the layer to dry. Add another layer of color if you want a richer or darker appearance.
Apply a thin layer of finishing spray once the color has completely dried.
Allow the seats to dry. Wait approximately 48 hours before setting in your seats or reattaching them.
