While building our house, my car would sit in the sun for hours on end, everyday for over a year. As a result of not having the time to properly care for my car, there is a narrow strip on my dash that when viewed at an angle, has a dry look to it. Straight on, it looks like any other part of the dash. Is it possible to "rehydrate" that part of the dash and if so, what would I use? It bothers me every single time I look at it. The dash material is a soft textured plastic/vinyl.
