17p for candy lime green. The problem is most of the companies sell this as a three step paint. You would need a robot to apply it thin enough to look decent.
With that in mind, the best alternative I have used is nail polish I swiped from my granddaughters collection. She bought it and said, "Look...it's Ninja green!"
I'll apologize, in advance, for it's name. The polish is called "Sinful Secrets" and the color is "Happy Ending green". It's almost 100% accurate and it's easier to apply than the three step stuff. Even the metallic particles match.
You are on your own if your wife sees the credit card statement. I have the three step kit. This is cheaper, and looks better.
