Never quite understood the vinyl roofing on station wagons thing(Vinyl tops originally being artificial convertible tops)but you,ve done either an exceptional job of reroofing this wagon;or taking very good care of it all along.
It was pretty wasted when I got it, but it had no tears. I used McGuiar's Vinyl Restorer and it came back beautiful.
When i bought the wagon the vinyl roof was pretty dirty. All I did was wash it and put McGuiar's Vinyl Restorer on it and it came back very good. I spray some on about once a week to keep it shiny.
