Vinyl Paint

Just picked up a 70 Dart that needs the front bench seat recovered, back is fine. Looking at a front bench about 60 miles away for $275, and then last night I catch an ad on craigslist for Dart buckets 5 miles away for, (side down before reading further) ......... $100 in very good condition, >>including the tracks. Just got home with them, in great shape but white. What is the best vinyl coloring to use to get them black.
