We have a friend in our little Pontiac club, he owns a 71 LeMans 400/4-speed. The car is black and he also uses this product and it looks incredible. Funny story that fits in here. He had Craigers with white letter tires on the car for years. All the shows we went to together he never won anything. I sold him my Rally II's off the Firebird last year and he just put them on leaving blackwalls out. Went to a two day car show this past w/e and won a top 20 trophy. So he is now happy about the Rally II's and blackwalls out. We busted his "stones" for the past three years about his Craigers and white letters.
I'll see if I have a pic of his car just after using the Zanio, it looks AMAZING!
