Many times with leather . the dying process need the leather to be dried. Then like a leather cathers mit linseed oil has to be added to keep the leather soft.They say the seats are dyed at the factory, but leather may actually take a different color product/process. They say vinyl dye works on leather, but it is really for vinyl. Many times it will work on leather and the paint store said I should not have a problem, but it just kept flaking off my leather. My truck is a work truck so I still have not redone to seat dye/stain/paint. My flaking on the leather started immediately after applied, but it is still perfect on the vinyl portions.
Found a dealer near me. Went this AM and got a spray can of the stuff. $11.00 and change. Say's on the can that the can has to be at least 70 degrees. Soon's it warms up a little here I'm going to try it!!Can you ballpark the cost per can?
