wrapping works yeah, but race teams can cope with rebuilding an engine after each race if they have to, or in this case replacing/repairing cracked headers etc. whereas car manufacturers aim for longevity/reliability with their products. thats why high end manufacturers opt for the coating and also why its probably a better choice for street cars
