HOW TO RESTORE AUTO LEATHER
Submitted by DB / 07-31-06


This depicts restoration and re-dyeing of leather seats in a 1990 Lincoln Town Car Cartier. The driver’s seat was worn and torn and the passenger’s seat had some cracks. The pictures are of the driver’s seat.


Tools You Will Need

  • 8 ounces of Rejuvenator Oil
  • 8 ounces of Prestine Clean
  • 8 ounces of Prepping Agent
  • 2 ounce jar of Crack Filler
  • 8 ounces of Custom Color dye – cut a snippet of leather from under the seat and mail with your order. The dye match on my car was perfect.
  • You can order all the above from Leatherique.
  • 1 spray bottle
  • Small tube or bottle of Super Glue
  • Soft leather for patching
  • One sheet of 400 wet/dry sandpaper
  • Cotton terry hand towels and wash cloths
  • 2-inch brush for applying the color
  • Tear Mender fabric & leather repair adhesive
  • Go to www.tearmender.com/WhereToBuy.htm
  • Contact cement
*Note – Use Tear Mender if you plan on doing the leather repair with the covers on the seats. Use Contact Cement if you plan on removing the leather covers.

Let's Get Started

Remove the seats – or not

In this repair the driver’s seat was removed and the passenger’s was not. Removal is straightforward; four bolts and unplug the electric harnesses from the seat motors.

It is easier to work on seats on a workbench but I wouldn’t have removed the seat if I hadn’t planned on removing the covers and repairing them from the underside.

Clean and prep the leather

Vacuum seats and brush all dirt and crumbs, etc. from the seams. Clean seats thoroughly with hot water and dry with a towel, then let air dry.

Scrub the leather with lacquer thinner and medium steel wool or a Scotch pad. This will remove silicone and deteriorated dye. Working on a bright day provided lots of good light, which you need. Do not abrade the leather. Remember that lacquer thinner is combustible. Keep it away from drop-lights or anything that could cause the fumes to explode. Leave the engine and radio OFF.

Thoroughly wet-sand with 400. Removing most of the original finish will make the leather permeable and permit rejuvenator oil to soak in freely. The permeable surface will also allow new dye to go on smoother and adhere better. Completely sand the entire seat. Don’t skip over areas that are in good condition. Don't try to sand out scratches. They must be filled. Clean the leather with damp towels and allow to dry. Allow 24 hours in warm, dry weather.

Apply rejuvenating oil

Apply Leatherique Rejuvenating Oil liberally and rub it in with your hands. Squirt it onto the leather from the bottle, quickly smearing the heavy liquid before it can run. Where it quickly soaks into worn spots, apply more during this first application.

If rejuvenator oil is still sitting on the surface in places after the rest has soaked in, give those places another good wet sanding. Work quickly and keep wipe up water as you go so the leather won’t become saturated. Wipe it clean, allow it to dry an hour and re oil.

Park in the sun, cover the seats with plastic trash bags and let it cook for 24 hours before going to the next step.

Clean with Leatherique Prestine Clean

I put the cleaner in a spray bottle but you can squirt it on if you like. Spray liberally and scrub surfaces thoroughly with a cloth wet with Prestine Clean. Follow as you go with a damp towel. Rinse the cloth often and wring thoroughly.

You can use Prestine Clean on vinyl and plastic, too. Clean the steering wheel while you’re at it.

Wait two days before proceeding to prepping the surface!

Prepping the surface

Apply prepping agent to a cloth and to remove any remaining silicones, waxes or other contaminants. Wash cloth frequently. Buff prepped leather with a dry towel. No need to wait for the next step.

Repairing cuts

A cut or hole in the leather must be repaired with a patch on the underside. Any place where the leather is weakened should be patched. Slice through with a razor blade to gain access to the underside.

Get a thin scrap of leather from Tandy, The Leather Factory, a craft shop or other source. I purchased a leather coat from The Salvation Army for $5.00. The leather was very soft and the coat was in bad shape. Now it’s in pieces.

The patch must be larger than the cut, of course. Work the patch into the hole so it can be glued to the underside of the seat leather, fuzzy sides together. Use Fabric Mender if you are patching from the top.

Do not use contact cement because it adheres instantly when the two surfaces touch and what will happen is so bad you don’t even want to think about it.


I had intended to repair this seat from the bottom but encountered stitched on padding when I started taking it off. If I had it to do over I would cut through the padding, apply the patch using contact cement, and then use contact cement to re-apply the padding.

Holding up the seat leather, work the patch into place with tweezers or a knife blade and apply the glue to the underside edges of the hole. A finger can do a good smear job. Then press the two pieces together. The glue sets up quickly so if it isn’t right, pull it away and start over. After the glue is dry put a small bead of Super Glue in the seam (spreading it with your fingers) and then push the seam together. Super Glue was originally invented to close flesh and internal wounds without stitching. Fill the repaired cut with filler as described below.

Important: Remove any excess glue using a razor blade; pull it away from the leather using tweezers and cut it off. Dye will not cover contact cement or Fabric Mender.

Fill cracks and scratches with crack filler

For large cracks, apply flexible filler inside the crack, then level with a spatula made from a credit card or hotel key card cut lengthwise. Use very little filler. Repeat this process until the surface is smooth. Using a damp rag, remove filler on the surface outside the crack before it dries. Allow to dry a half hour and sand, wet, with 400 sandpaper.

Even light scratches and roughened areas will take more than one application. Dye will not fill any surface imperfections, not even faint spider-web cracks. so fill and sand.

Allow the filler to dry overnight before sitting on a seat that has been filled. Let dry two days before dyeing.

Dyeing the leather

Wipe all surfaces with a damp towel to remove dust. Shake the dye thoroughly and strain into a small plastic container. Refill the bottle and shake again . Then pour about 2 ounces into the plastic container. I found that the dye went on smoother when thinned with about 2 ounces of water to the 8 ounces of dye.
Work quickly. Once dye is brushed on it begins to dry fast. You can't go back over an area after more than a minute or so without leaving brush strokes. Use your finger to wipe away dye that runs into the seams. Pull the seams away to work the dye in. Don’t let it puddle. On the seat back, be sure the seat is laid well back so that it is separated from the bottom. Otherwise, the dye will cause the seats to stick together and may leave a messy appearance.

You will need to apply at least two light coats. Light coats! Brush in the same direction. You can cross-hatch before the dye starts to set up to work the dye into the surface, but finish brushing in one direction. Allow at least half an hour to dry before applying the second coat.
