After reading lots of very positive reviews I used SEM interior spray dyes/paints. they also supply plastic parts cleaner and adhesion promoter. I had friends who used it on everything including steering wheels with no chipping, flaking ever. I used it on almost everything in my interior with no problems yet after 3 years. You can get SEM at professional upholstery shops or supply places. There are tons of shades and different gloss levels of clear to spray over the colour if you wish. I have lots of info on my use of it on my pages. http://www3.telus.net/68bird/interior_work1.htm I would consult an upholstery shop on the best way to remove your old colour. good luck.
