If it's a solid colour it's not necessary to have a clearcoat(however they may clearcoat it anyway)unless it's a tri-coat system which would be odd as I'm pretty sure it's the same code used for the milano red integras, I could be wrong. It would make sense to clear coat a red as it's well known how the pigments in red paints are prone to "premature" aging/fading.
I consider myself quite picky when it comes to paint and some of the work I've seen was very good. It has all been on single stage paints though. Honestly I would be a bit hesitant to use such a service for metallic paint unless I saw their work before.
