Anybody ever dye carpet?
 

I have an 83 Cab. Overall the carpet is in very good shape except the black is fading to brown. Especially on the back of the rear seats and rear deck.

I'm looking for a cheap fix for a while. I plan to do a carpet and paint job with new rubber seals over the next year or so.

I was in the grocery store and picked up some fabric dye which I might try. I've used this before, but not on something that I can't remove.

Indelible ink "sharpie" works well in spots. Is the ink avalible in pints.
I'll try anything!
Thanks!
