My dad has two cars that are usually only driven to car shows. A red 1965 GTO conv. and a red 1993 Mustang Cobra. In the past I have used Clearkote's wax. It's reorder time, and wanted to get some options before I ordered more wax.
For red you really can't go wrong with Pinnacle Souveran. It is outstanding on red. That is only if you intend to go the wax route. Wolfgang is also fantastic on Red and would last a lot longer. If I had a red car it would wear Wolfgang every day of the week.
I have a Vibrant Red 1993 Mustang GT convertible, the same color as the '93 Cobra. I use Pinnacle Souveran paste with quick coats of Liquid Souveran Spray at shows. I think that makes this specific color look fantastic.
