I did it. Ordered the kit from Leathermagic
Leather Refinishing Kit | Dye, Painting, Recoloring & Restoration | Stain for Furniture, Automotive and Other Uses.
It's a good idea to order an extra 8oz bottle of dye. I used a fair amount on the first seat and didn't have enough to finish the second. I could've stretched the dye for both but I liked the look after an extra coat of dye.
