I just touched up the leather seats in My 2004 Lexus with SEM Leather Dye (Waterborne). It worked very well by completely prepping and sanding (with 400 grit Wet sandpaper) before respraying .I had mine custom mixed by taking a headrest for them to go by. I had used the SEM vinyl and carpet spay in other vehicles,but just recently found they made leather dye. Larry
