The different pieces fade at different rates depending on the material. I just re-dyed a 70 red interior with SEM red, check their chart for a match. Did all the dash, door panels seats, kick panels, steering column. Looks like new. Preparation is the key, degreaser, dawn soap works well too. Light even coats just enough to cover. Available from you auto paint supply store. 2 cans should do it, about $25.
