About a month ago, I bought a set of stock seat belts from Craigslist. They came out of a 69' Chevy Truck and were really in need of reconditioning. Luckily, the retractor boots were in great shape as were the buckle covers, GM push buttons and chrome ends. I had heard so many good things about RIT Fabric Dye, I thought I'd give it a try. Because the belts were originally parchment in color and stained pretty bad, I used 2 packs of RIT Dye and then followed the rest of the manufacturers directions. For the plastic pieces, I used Rustolem Paint for Plastic. Pictured are before and afters.
