I was wondering if anyone on here has dyed their seats or carpets before and what they used I dyed my black Na seats that had turned blue because of the sun last year and after just 2 months they were back to blue. I had used a spray on dye it worked very well on the carpet but the seats didn't last. any permanent solution ? I don't want to have to keep taking my seats and carpet out of my car to dye them lol.
