Few questions about dupli color mirage paint?

[XMODSaretheBEST]

For those of you who have used dupli color mirage paint, i have a few questions.

1. how much is it?
2.Does it look good on xmods?
3. Do i apply the top coat that it comes with?
4.For the purple/green kit, does the color go from purple to green or green to purple?

I want the car to look purple most of the time (like in dark areas)

Twenty bucks for the kit. You must use the clear that comes with the kit. I think the color flops from purple to green but I am not sure.
