Cracked leather seats can significantly decrease the value of a car, as well as being an eyesore. However, you can repair your leather seats using a variety of simple materials found at an automotive paint store. This process takes about 2 hours and will leave your leather car seats looking as good as new.

1. Step 1

   Combine a few drops of dish soap with warm water in a large bucket. Dip the scrub brush into the soapy water and scrub the entire leather car seat clean, making sure you get in all the crevices. Dry the car seat thoroughly with the terry cloth.

2. Step 2

   Dip the scouring pad into the soapy water now and clean the entire seat again using circular motions. This picks up any dirt you may have missed previously and helps prep the seat for the new dye. Dry the seat thoroughly with a clean towel.

3. Step 3

   Apply a small amount of denatured alcohol to a clean paper towel and wipe down the entire cracked leather car seat. Before it can dry, re-wipe the seat with a clean, dry paper towel. This removes any silicone or other chemicals that may prevent the new dye from holding.

4. Step 4

   Dip the 240-grit sandpaper into the bucket of soapy water and begin to sand the areas of the car seat with cracks. Before long, the dye will begin to move around under the sandpaper. Use the sandpaper to move the lifted dye into the cracks as filler. Continue until the leather begins to smooth. Wipe the car seat down with a towel and then use a blow dryer to completely dry the car seat.

5. Step 5

   Apply a thin layer of SEM Leather Prep to the chair using the manufacturer's instructions. This will prepare the leather even further for the new dye. Use a paper towel to apply a thin coat of Thompson's Sport Seal to the damaged area of the car seat to protect the raw leather. Allow it to dry before continuing.

6. Step 6

   Cover all areas of the car surrounding the cracked leather car seat with an old sheet to protect them from the spray dye. Hold the SEM Classic Coat dye 10 to 16 inches from the damaged area of the car seat and use short bursts to begin dyeing the seat. Once a thin layer has been applied, use the blow dryer to dry it, and then apply another thin layer. Ensure that all cracks are filled in, if necessary, by spraying heavy coats of dye directly into the cracks.

7. Step 7

   Apply a thin coat to the other visible areas of the seat to make the color uniform with the previously damaged area. Allow the leather seat to dry for several hours before driving.
