Repairing this damage took a few more coats than usual, 7 before full coverage was achieved, but still an incredible transformation! Because the damage had exposed bare leather, the leather was first sanded with 400 grit sandpaper, 3 coats applied, and then sanded again with 400 grit. The surface is again smooth! We have hundreds of different leather dyes for GM vehicles, so if you need touch up dye for your Buick, Cadillac, Chevrolet, GMC, Hummer, Pontiac, or Saab, click here to order!
