I am an aspiring classic car collector and restorer. Hobby restorer is more like that. Many of my fellow vintage trainers have recommended using Blackrock when restoring these classic bags, especially when the bag's color has faded. Before and after photos of my VERY FIRST restoration project and I'm SUPER IMPRESSED at how well it turned out. I used Blackrock on all the faded areas especially the edges and all over the bag especially the faded areas. A LITTLE of this product goes a LONG WAY! I restored a few more packets and have half a glass left! I love this stuff!
