So I have been working on my 86 ssp recently and had a thought. The interior was originally grey and tan. Which I am not to fond of, but I do like black and tan. So my question is has anyone here used dye to change the color of their seats or any interior pieces for that matter? I have heard it used on carpet. Thoughts? Good or bad idea?? Rite dye or leather dye??
