Hi, I have a C43 with saddle leather. The bolster is starting to wear through the color and I want to get a repair dye before it gets any worse. I tried https://www.seatdoctors.com/ but the color isn't an exact match and the sheen is way off. The seats are a really flat sheen and even his matte covering still had a glossier look to it. Does anyone know who makes the best match? Any help would be appreciated! Thanks.
