i was wondering who has played around with the sem products? i have a pain in the neck color for my car Briar Brown only made for 2 years. which i love because its not common but tracking seat upholstery is even harder. so I'm thinking of using SEM dye but they don't make a Briar Brown. what i have found that looks somewhat close is SEM 15023, Cordovan Brown. has anyone used this color before in place of the briar brown or do someone else make a dye that is Briar brown. i only have the rear seat bottom to color and its current color is dark blue.
