I found a good deal on some corbeau seats for my car but there is one issue with them. One seat is nice and black and the other one is a faded black (has brown tint). I was looking up seat dye and came across a product called simply spray fabric paint,has anyone used it or any fabric paint and how did it hold up? Trying to decide if i should buy the seats or not.

I've never heard of it, but that doesn't mean it's no good. I'd get some very good cleaner, and a couple cans of SEM Leather & Vinyl paint, wait for a nice sunny day, and have at it.
