Interior color Dying...Good/Bad?

I have a 78 Mustang II...White outside and Aqua interior. Well as we know over the years mother natures sun fades our interior. My interior is like a dark blue on the bottom and lighter blue on the top part...If ya know what I mean. Was wondering what is the best way to dye my interior close to the same Aqua or a nice blue so its one color. just seeing if anyone has done this before and what it took....thanks!!

When I was working for a body shop we used Marhyde from the paint supply place It worked great on soft vinyl like dask pads or door panels, I think the good results were from good prep. We never did find anything that would work good on the milk jug type plastic like your kick panels or the rear compartment panels. Tried all their magic prep solutions but it would still peel right off. Times have changed they might have something better now. Try to spray a sample on the back of a kick panel and see if it scratches off easily.
