My paint for the interior came from Chevy Duty and was manufactured by Sherwin Williams. They recommend using reducer and hardener from the same manufacturer. The ratio was 8:4:1 with 8 parts paint to 4 parts reducer to 1 part hardener. Also, if you're looking for Juniper Green or any paint close to the original, you might look at Jim Carter or Chevy Duty. I can't find anyone that has Burgundy Maroon except Carter. However, when I had my paint mixed last time I painted it, I didn't go to an old car/truck store. The paint was too red and it taught me a lesson. If you want it right, go to the vintage parts places and buy it there.
