anyone ever removed vinyl dye from seats and not ruined the vinyl? I've searched online and keep seeing use acetone zylene? and thinner or even mineral spirits. I figure those would remove the dye but worry about ruining the material. I ask because I got a 79 trans am, seats are perfect, but they are red, I'm not fond of red interior, plus they are dyed red, I can see black showing like in the zipper seam in back and like on the bottom. If they were actual red viyl covered I would leave them. BUT they are dyed so I'm thinking either remove it so they'll be black, which is what I want, or redye them black. The back I'll have to do black regardless because they were white, but I can see some black on them and then the red.
