That's great, but you're gonna need LED's to power through that many layers. Polishing does nothing for light output. A buddy of mine over-tinted his lights and got rear ended. His insurance company denied the claim and he paid out of pocket for the repairs to the other car. He's still paying for his totaled truck.
Find't change my Sig. But, I did polish the roof rails and B-pillars & I got a mirror polish on the tail lights. Go me =]
