Leather treatment on BMW e34

After 5-10 years, the seats of your Bmw E34, E32 will probably look like mine, with small cracks and discoloration. It is time to renew this leather. I bought my products from Leatherique.

Procedure

Leatherique products 300 and 500 grits sand paper Terry Towel or soft cloth

1. This is my seat before applying the leatherique products. You can see the difference of colors and little cracks. 2. Vacuum the surface of the seats well or use a soft brush to remove large particles of dirt, paying particular attention to seams, folds, and cracks.
2. Apply the Rejuvenator product on all seats with your bare hands, massaging the leather. 3. You have to let the car sit in a warm spot (sun will be perfect)to have a greenhouse effect, for a day. In cooler weather, or for long-term storage in a garage, cover the seats with plastic wrap, and "warm" with a hair dryer.
4. The seats absorbed the product and the leather is softer. What you see is simply the dirt, grime, air pollution, perspiration, salts and other toxins that have floated out of the leather to the surface. If you don't dye the leather, Apply Prestine Clean by hand or with a soft Terry Cloth towel and massage out the dirt.
5. Using 300 grit, lightly wet sand the leather to smooth out any cracks and hangnails in the surface, and to remove the surface of the old dye and as much of the old dye that is loose and worn from age. Do not attempt to cover over damaged dye. 6. Apply another coat of Rejuvenator as the seats will absorb it right away.
7. Apply the Prepping Agent liberally with a terry towel or shop rag, and clean to remove any remaining dirt, ensure the top layer of old dye is broken down. Resand with wet 320 if needed . If you are filling cracks with crack filler, this is the time to do that step. Apply crack filler only into cracks only. Allow to dry 20 minutes and refill as necessary. Resand with 500 for a smooth, flawless finish if needed. Let it sit overnight or about 6 hours to allow prepping agent and crack filler to dry.
8. Brush (top quality synthetic, acrylic type brushes) or spray on your new dye in a dirt free environment, preferably indoors. Thin dye to prevent heavy buildup of color. Temperature of 20-30C (70-85F), low humidity, no rain. 9. Let it sit for 48 hours then buff it up with a lint free cloth. Use Prestine Clean in the future for maintenance (in a year). WHAT A DIFFERENCE!!!
10. The only mistake I have done is that I should have cut the die with water, it was too thick so you can see the brush pattern. I sanded the seats with 500 grits sand paper until the seats are smooth to the touch... hummmm, I love that.
