I really like them too, hey maybe I lissed it, but what is the best stuff to put on them to keep them from drying out and in good shap
Other than the Turtle Wax product that was mentioned I used to use a product that is still available today to clean (not dress) all vinyl; tops, dash, seats,etc.. It's called Murphys Oil Soap, it is a mild soap made with a gel/oil base and it now comes in two varieities, a gell and a pourable solution, mix either with a small (qt.) of hot water. This is not a harsh cleaning solution and the oils of the product do absorb into the vinyl. As far as a dressing from todays product there are a great variety to select, can't say if one does any better than the others? But DO NOT use any dressing on your seats or sterring wheels
you'll be sliding all over the place.
